Implement layout logic for vectors, matrices and default-stride arrays.
Custom stride arrays are complex, and will be tackled as a followup change.
This change also emits byte offsets for all structure members as comments. This is even emitted for non-storage uses, which can be cleaned up as a followup.
Fixes a whole lot of TINT_ICE() for non-complex WGSL shaders.

The readers must not produce invalid ASTs.
If readers cannot produce a valid AST, then they should error instead.
If a reader does produce an invalid AST, this change catches this bad behavior early, significantly helping identify the root of the broken logic.
IsValid() made a bit more sense in the days where the AST was mutable, and was constructed by calling setters on the nodes to build up the tree.
In order to detect bad ASTs, IsValid() would have to perform an entire AST traversal and give a yes / no answer for the entire tree. Not only was this slow, an answer of 'no' didn't tell you *where* the AST was invalid, resulting in a lot of manual debugging.
Now that the AST is fully immutable, all child nodes need to be built before their parents. The AST node constructors now become a perfect place to perform pointer sanity checking.
The argument for attempting to catch and handle invalid ASTs is not a compelling one.
Invalid ASTs are invalid compiler behavior, not something that should ever happen with a correctly functioning compiler.
If this were to happen in production, the user would be utterly clueless to _why_ the program is invalid, or _how_ to fix it.
Attempting to handle invalid ASTs is just masking a much larger problem.
Let's just let the fuzzers do their job to catch any of these cases early.

The chromium tests for static initializers get upset about the call to
ClassId::New() in a global variable initializer.
Instead, take the address of a unique 'token' variable to generate the
unique identifier.
This is similar to how things were before
https://dawn-review.googlesource.com/c/tint/+/42460
but of taking the address-of the token in the header, we're instead
taking the address-of inside the cpp file, avoiding the DLL issues
that 42460 addressed.

This CL removes the registration of functions to after the function body
has been processed. This allows us to catch recursive calls where the
function calls itself. Prior to this we'd find the called function and,
if the function was an entry point, end up in a loop trying to walk all
the callers. With this change, the function is not found when we do
the lookup and we exit as expected.

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.

Resolving these at TD time removes swizzle parsing in the HLSL writer, and is generally useful information.
If we don't sanitize in the TD, we can end up trying to construct a resulting vector of an invalid size (> 4) triggering an assert in the type::Vector constructor.

IdentifierExpressions that resolve to functions and intrinsics were not being assigned a semantic::Expression as there is no function / intrinsic type to give them. This lead to NPEs in the writers when these identifiers were reached and TypeOf() is called.
Adding a new tint::type::Callable is an option, but until functions become a type in the language, this seems like a very large and debatable change.
Attempting to detect IdentifierExpressions with no semantic node in the validator is another option, but this is clunky as it has to detect incomplete semantic info from the TD, and cannot identify whether this actually resolved to a function or an intrinsic.
Instead we now error in the TD if encounter an IdentifierExpression that resolves to a function or intrinsic which is not called (ident is not followed with parenthesis).
