Instead of emitting all global variables and then functions, emit
global declarations in the order they were added to the AST.
This fixes issues where the reording might generate an invalid WGSL
program from a valid input (e.g. when declaring a global variable with
the same name as a variable inside a function that precedes it).
This also unifies the implementation of Generate() and
GenerateEntryPoint(), to avoid implementing the same logic twice.

While traversing and resolving the AST, TypeOf() was called to look up
the semantic node for the given AST expression in order to fetch the
resolved type. However, for CallExpression semantic nodes are
constructed at the end of the AST traversal, and GetType() for these
would unexpectedly return nullptr, causing a crash.
To fix, have TypeDeterminer maintain an internal map of ast::Expression
to resolved type. Always populate this internal map whenever SetType() is
called. At the end of the AST traversal, have CreateSemanticNodes()
construct the semantic nodes for any ast::Expression nodes that do not
already have a semantic node assigned.
With this, GetType() will always return the type set with SetType().

Provides a centeralized table for all intrinsic overloads.
IntrinsicTable::Lookup() takes the intrinsic type and list of arguments, returning either the matched overload, or a sensible error message.
The validator has expectations that the TypeDeterminer resolves the return type of an intrinsic call, even when the signature doesn't match. To handle this, create semantic::Intrinsic nodes even when the overload fails to match. A significant portion of the Validator's logic for handling intrinsics can be removed (future change).
There are a number of benefits to migrating the TypeDeterminer and Validator over to the IntrinsicTable:
* There's far less intrininsic-bespoke code to maintain (no more duplicate `kIntrinsicData` tables in TypeDeterminer and Validator).
* Adding or adjusting an intrinsic overload involves adding or adjusting a single Register() line.
* Error messages give helpful suggestions for related overloads when given incorrect arguments.
* Error messages are consistent for all intrinsics.
* Error messages are far more understandable than those produced by the TypeDeterminer.
* Further improvements on the error messages produced by the IntrinsicTable will benefit _all_ the intrinsics and their overloads.
* The IntrinsicTable generates correct parameter information, including whether parameters are pointers or not.
* The IntrinsicTable will help with implementing autocomplete for a language server

Make private all TypeDeterminer::DetermineXXX() methods, forcing all tests to use the root-level TypeDeterminer::Determine() method.
Remove TypeDeterminer::RegisterVariableForTesting().
The main use for calling the TypeDeterminer::DetermineXXX() methods was to perform type determination on a partial AST.
This was messy and often resulting in multiple calls into TypeDeterminer. Most tests already perform a full TypeDeterminer::Determine() call when the program is built, so many of these were redundant.
The exposure of these internal methods for testing also makes refactoring the TypeDeterminer extremely difficult.
Add a number of ProgramBuilder helper methods for attaching the partial AST in these tests to the root of the AST, greatly simplifying the use of the TypeDeterminer:
* ProgramBuilder::Global() and ProgramBuilder::GlobalConst() are helpers that register the variable returned by ProgramBuilder::Var() and ProgramBuilder::Const(), respectively.
* ProgramBuilder::WrapInFunction() is a variadic function that accepts variables, expressions and statements, attaching these to the root of the AST via a dummy function.
Most test classes now no longer use their own TypeDeterminer, and instead properly depend on the automatic type determination performed at Program build time.

(especially around AppendVector()).
This is now required as semantic information is generated inside the
writers for newly constructed AST nodes, and we need to register
this semantic info so it can be fetched later.

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.

A container and allocator of objects of (or deriving from) the template type `T`.
Objects are allocated by calling Create(), and are owned by the BlockAllocator.
When the BlockAllocator is destructed, all constructed objects are automatically destructed and freed.
Objects held by the BlockAllocator can be iterated over using a View or ConstView.
Use this to hold the ast::Nodes in the ast::Module
This is called BlockAllocator as it can be optimized to hold objects in contiguous memory blocks, which will improve cache coherencey. Currently BlockAllocator is a straight port of the vector-of-unique-ptr, taken from 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.

The latter also provides a diff when two strings do not match.
Refactor these to:

auto expect = yyy;
EXPECT_EQ(got, expect);
So that the error message clearly shows which one is the generated, and which one is the reference.
