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

This CL removes the registration of functions to after the function body

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.

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).

If the parser hits a `maximum parser recursive depth reached` situation, then we need to try and resynchronize the parser.
If we fail to do this, then the synchronized_ flag may remain true, and the parser will believe progress is still being made.
In this situation the parser may try to reparse the same token, forever.
By calling sync_to() we either find the end of the block, and forward progress can be made, or synchronized_ is set to false, and the parser can error out cleanly.
