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

To avoid breaking things, functions that return the type cast away

AST nodes must not be shared. Diamonds in the AST will cause all sorts
of exciting, non trivial bugs.
All AST nodes must be reached by the Resolver. There are two common
reasons why they may not be:
(a) They were constructed and not attached to the AST. Several
transforms scan the full list of constructed AST nodes to find nodes
of a given type. Having detached nodes will likely cause bugs in
these transforms. Detached nodes is also just a waste of memory.
(b) They are attached to the AST, but the resolver did not traverse
them. Having the resolver skip over parts of the AST will fail to
catch validation issues, and will leave semantic gaps, likely
breaking downstream logic.

This makes the .cc files match the header file name, which allows for
the text editor "header flip" feature to actually work. The reason these
files were named this way was because GN doesn't allow name conflicts in
the same source set, despite the files being in different directories.
This change splits the files into different source sets. To do so, we
use GN templates, which also reduces duplication in each target
definition.

EmitControlBarrier() was calling MakeOperand() to create ast::Expressions that held a ScalarConstructorExpression, which held a IntLiteral.

The CloneContext will currently de-duplicate any pointers that are cloned multiple times, however this isn't ideal behavior for AST nodes.
AST nodes must be unique in the tree, so a non-transform clone of the AST from one program to another should only ever Clone() called once per node. Hitting the map for these is inefficent, worse still, there are cases in the transforms where we actually *want* to create N copies of the same source node. The current implementation makes this impossible.
This change introduces ShareableCloneable, a new base class that derives from Cloneable.
Repeated calls to CloneContext::Clone() for Cloneable pointer types will now produce a new, unique instance per call.
Repeated calls to CloneContext::Clone() for ShareableCloneable pointer types will de-duplicate as before.
type::Type objects are shared, want deduplication while cloning, so now derive from ShareableCloneable.
ast::Node continues to derive from Cloneable.

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.

When finding the true-head, false-head, and potentially the
premerge-head blocks of an if-selection, there was an overly
aggressive check for the true-branch or false-branch landing
on a merge block interior to the if-selection. The check was
determining if the merge block actually corresponded to the selection
header in question. If not, then it was throwing an error.
The bug was that this check must be performed only if the
target in question is actually inside the selection body.
There are cases where the target could represent a structured
exit, e.g. to an enclosing loop's merge or continue, or
an enclosing switch construct's merge.
There is still a latent bug: if either the true branch
or false branch represent such a kLoopBreak, kLoopContinue, or
kSwitchBreak edge, then those are not properly generated.
That will be fixed in a followup CL.

* It didn't always produce valid WGSL (crbug.com/tint/687)
* It didn't handle builtins as entry point parameters
* It used hard-coded symbols that could collide
* It didn't use DataMap for input.
The new implementation addresses all of this.

Use the new CalculateArrayLength and DecomposeStorageAccess transforms to simplify storage buffer patterns before running the HLSL writer.
The HLSL writer now handles the InternalDecorations for the internal load, store, and buffer-length intrinsics.
GeneratorImpl::EmitStorageBufferAccessor() has now been entirely removed, as all this primitive load / store decomposition performed by DecomposeStorageAccess.
TODOs around runtime arrays have been removed, as this is now handled by CalculateArrayLength.

HLSL has some pecular rules around structure constructors.
`S s = S(1,2,3)` is not valid, but `S s = {1,2,3}` is.
This matches the quirkiness with array initializers, so adjust the array
hoisting logic to also support structures.

HLSL's matrices are declared as <type>NxM, where N is the number of
rows and M is the number of columns. Despite HLSL's matrices being
column-major by default, the index operator and constructors actually
operate on row-vectors, where as WGSL operates on column vectors.
To simplify everything we use the transpose of the matrices.
This is the same approach taken by SPIRV-Cross.

Registering a new Symbol with the NameFor() of the source symbol creates
a new *named* symbol. When mixing these with unnamed symbols we can have
collisions.
Update CloneContext::Clone(Symbol) to properly clone unnamed symbols.
Update (most) the transforms to ctx.Clone() the symbols instead of
registering the names directly.
Fix up the tests where the symbol IDs have changed.
Note: We can still have symbol collisions if a program is authored with
identifiers like 'tint_symbol_3'. This will be fixed up in a later
change.
