Remove all sem::Type references from the AST.
ConstructedTypes are now all AST types.
The parsers will still create semantic types, but these are now disjoint
and ignored.
The parsers will be updated with future changes to stop creating these
semantic types.
Resolver creates semantic types from the AST types. Most downstream
logic continues to use the semantic types, however transforms will now
need to rebuild AST type information instead of reassigning semantic
information, as semantic nodes are fully rebuilt by the Resolver.

All that remains in the wgsl parser that references sem::Type* are
the register_constructed funcs/types, and adding an ast::ExternalTexture
type.
Also:
* Added specialization of OperatorArrow for type::TypePairs that returns
the value by reference so that operator-> can chain properly.
* In a few places where we expect the type to implicitly cast to a
pointer for a bool expression, e.g. `if (type)` or `TINT_ASSERT(type)`,
I added access to the `.sem` member of the TypePair. I tried adding an
implicit cast to bool, but this results in ambiguity in gtest for
equality comparisons.
* Constified more type pointers in type nodes
* Replaced header includes with forward declares in wgsl/parser_impl.h

SymbolTable::New() used to build and return a symbol without a registered name. When you asked for the name of the symbol it would return tint_symbol_N, where N is the numerical identifier for the symbol.
This approach was a major tripping hazzard for transforms that liked to fetch the source program name, and register it in the new program (in this situation, you should always use `CloneContext::Clone(Symbol)`).
Without special casing for unnamed symbols, you could end up promoting the unnamed symbol to a named symbol, and then colliding against a new unnamed symbol.
This is exactly what happened in tint:711.
Instead, with this change:
* The concept of unnamed symbols has been removed. All symbols now have a name.
* The signature of `SymbolTable::New()` has been changed to take a name parameter (which defaults to 'tint_symbol'). This can be used to create a new, unique named symbol (possibly with a suffix), which will not collide with any existing symbols. Note these symbols may still collide if `SymbolTable::Register()` is called with the same name. All Transforms that currently use `SymbolTable::Register()` will be fixed in another change.
* The CloneContext has been updated to use `SymbolTable::New()` instead of `Register()`. This means that any symbols defined before a clone will not collide.
* `CloneContext::CloneSymbols()` has been added which allows a transform to pre-clone all the symbols from the source program. This can be used to avoid the authored identifiers being suffixed with a number, in the case a transform calls New() before the symbol is cloned.
* `Symbol::to_str()` has been changed to return `$<id>` instead of `tint_symbol_N`. This is to avoid any confusion between the actual name and the symbol ID.

We define the canonical type as a type stripped of all aliases. For
example, Canonical(alias<alias<vec3<alias<f32>>>>) is vec3<f32>. This
change adds Resolver::Canonical(Type*) which caches and returns the
resulting canonical type. We use this throughout the Resolver instead of
UnwrapAliasIfNeeded(), and we store the result in semantic::Variable,
returned from it's Type() member function.
Also:
* Wrote unit tests for Resolver::Canonical()
* Added semantic::Variable::DeclaredType() as a convenience to
retrieve the AST variable's type.
* Updated post-resolve code (transforms) to make use of Type and
DeclaredType appropriately, removing unnecessary calls to
UnwrapAliasIfNeeded.
* Added IntrinsicTableTest.MatchWithNestedAliasUnwrapping to ensure we
don't need to pass canonical parameter types for instrinsic table
lookups.
* ProgramBuilder: added vecN and matMxN overloads that take a Type* arg
to create them with alias types.

In anticipation of adding support for type inference, no longer use

use of that.
ast::Variable::type() has been renamed to ast::Variable::declared_type()
to help make its usage clear, and to distinguish it from
semantic::Variable::Type().
Fixed tests that failed after this change because variables were missing
VariableDeclStatements, so there was no path to the variables during
resolving, and thus no semantic info generated for them.

All includes from .cc to .h are preserved, even when transitively included.
It's clear that there are far too many includes in header files, and we should be more aggressive with forward declarations. tint:532 will continue to track this work.
There are, however, plenty of includes that have accumulated over time which are no longer required directly or transitively, so this change starts with a clean slate of *required* includes.

This change begins the work to move the reserved keyword remapping out of the writer and into the sanitizer transform.
If the transform::Renamer is in use, then these symbols should never have to be remapped - however for debugging purposes it is often nice to be able to emit code that isn't entirely mangled.

Transforms are meant to be reusable. Those that hold state cannot be used concurrently.
State leakage between runs is dangerous.
To fix this:
* Add transform::Data - A new base class for extra information emitted by transforms.
* Add transform::DataMap - A container of Data, keyed by type.
* Add a transform::DataMap field to Transform::Output.
* Have FirstIndexOffset emit a FirstIndexOffset::Data.
* Deprecate the getters on the transform.
Mutability of the transform config is also dangerous as setters can be called while a transform is actively running on another thread.
To fix:
* Expose a VertexPulling::Config structure and add a constructor that accepts this.
* Deprecate the setters on VertexPulling.
Also deprecate Transform::Output::diagnostics.
Put all the transform diagnostics into the returned Program. Reduces error handling of the client.

Despite `tint::ast::type::Type` being in the AST namespace, these classes are clearly not AST nodes:
* They don't derive from ast::Node
* They're deduplicated by the type manager
* None of the types have an Source - they have no lexical declaration point
* The fact we have `ast::Struct` and `ast::type::Struct` clearly demonstrates what is an AST node, and what is a type.
* We have code scattered in the codebase (TypeDeterminer, writers, etc) that create new types after parsing - so clearly not part of the original syntax tree.
Types in tint are closer to being semantic info, but due to the parse-time generation of types, and tight dependency of ast::Nodes to types, I'd be reluctant to class these as semantic info. Instead, put these into a separate root level `tint::type` namespace and `src/tint` directory.
The fact that types exist in the ast::Module has already caused bugs (https://dawn-review.googlesource.com/c/tint/+/37261). This is a first step in separating out types from the ast::Module.

The interface for cloning a module was made significantly more complex in https://dawn-review.googlesource.com/c/tint/+/35502/ as some of the transforms required constructing symbols before the clone. This was temporary solution in 35502 was to copy the symbol table, then construct the new types, then perform the clone. This lead to a really messy callback interface, that was extremely error prone (e.g. lamda-capturing stack variables from the initializer callback that had been unwound).
Instead, clone the symbols as they're encountered. This may produce an entirely different set of identifiers, but no longer ever-grows the symbol list, and keeps the interface clean.

two reasons:
(a) Performance is not important for testing, and this helps with
readability.
(b) A whole bunch tests were relying on std::move() clearing vectors so
they can be repopulated and used again. This is undefined behavior:
> Objects of types defined in the C++ standard library may be moved from
