And remove a whole load of const_cast hackery.
Semantic nodes may contain internally mutable fields (although only ever modified during resolving), so these are always passed by `const` pointer.
While all AST nodes are internally immutable, we have decided that pointers to AST nodes should also be marked `const`, for consistency.
There's still a collection of const_cast calls in the Resolver. These will be fixed up in a later change.

This is a modified version of the HLSL writer.
Basic types, arrays, entry points, reserved keywords, uniforms,
builtin uniforms, structs, some builtin functions, zero initialization
are implemented. Textures, SSBOs and storage textures in particular are
unimplemented. All the unit tests "pass", but the output is not correct
in many cases.
triangle.wgsl outputs correct vertex and fragment shaders that pass
GLSL validation via glslang. compute_boids.wgsl outputs a valid but not
correct compute shader.

WGSL:
* Remove vertex_idx and instance_idx.
These are now vertex_index and instance_index.
It seems this was removed once before, then reverted due to CTS
failures, but the original change never landed again.
* Remove the [[set(n)]] decoration. This has been [[group(n)]] for
months now.
API:
* Remove deprecated enums from transform::VertexFormat.
* Remove transform::Renamer constructor that takes a Config. This should
be passed by DataMap.
* Remove ast::AccessControl alias to ast::Access.

Allows transforms to assert their dependencies have been run before they
are.
Also allows the backends to validate that their sanitizers have been run
before they're used.

Adds additional modes to the Renamer for renaming just HLSL or MSL
keywords. The sanitizers no longer rename reserved keywords
automatically, which isn't usually necessary anyway since Dawn renames
all symbols.
The tint executable automatically renames reserved keywords when
targeting HLSL and MSL. It now also has an option to rename
everything, which is useful for testing the renamer.

Like 42264, this is an attempt to keep transforms immutable, and to keep mutable I/O information in Data objects.

Renames symbols.
Currently only supports renaming to a symbol with a monotonic increasing suffix.
