Integrates Tint repo into Dawn
KIs:
- Building docs for Tint is turned off, because it fails due to lack
of annotations in Dawn source files.
- Dawn CQ needs to be updated to run Tint specific tests
- Significant post-merge cleanup needed

StructMember, Type, Variable), such that all *Decoration classes now
subclass ast::Decoration directly. This allows for decorations to be

valid for both variables and struct members.
Checking that decoration lists only contain decorations that are valid

This change begins the work to move the reserved keyword remapping out of the writer and into the sanitizer transform.

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.
Add test case from fuzzer report.

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

The reason we need the sem_ prefix is because all the tint lib code is compiled as a single target, and .GN cannot cope with .cc files with the same file name, even if they're in different directories.
This could be fixed by building each directory as a separate target, but we have circular dependencies that currently make this impossible.

optional use of LLVM as a JIT-compiler by SwiftShader was dominating
compile times.
See the GN reference for details:
https://gn.googlesource.com/gn/+/master/docs/reference.md#the-all-and-default-rules
For now, it's equivalent to the "all" target. Note the latter is an
