Indexed draw buffer (color state) support on ES is not core until 3.2.
Previously, we were failing (asserting) if color state was changed for
a non-zero attachment. This CL compares the state, and only asserts if the
color state actually differs per-attachment.
It also implements a disable_indexed_draw_buffers toggle, which allows a
test to check for the functionality in a platform-independent manner.

Turns on Tint generation of SPIR-V if UseTintGenerator is on.
This affects SPIR-V generation for Vulkan, and SPIR-V passed
into SPIRV-Cross to produce GLSL.
It enables DrawTests use_tint_generator for Vulkan/GL where it
should have at least basic support.

This factors code to move parsing of tint::ast::Module to the
frontend. All backends will use this code path when
UseTintGenerator is enabled for both SPIR-V and WGSL ingestion.
To avoid too much code explosion, parsing and validating the
shader is moved into ValidateShaderModuleDescriptor which
returns a result struct that gets passed into creation.

EXPECT_THAT(xxx, Eq(yyy)) << ToString(xxx);
is a less-idiomatic way of writing:
EXPECT_EQ(xxx, yyy);
The latter also provides a diff when two strings do not match.
Refactor these to:
auto got = xxx;
auto expect = yyy;
EXPECT_EQ(got, expect);
So that the error message clearly shows which one is the generated, and which one is the reference.

This is a public API breaking change, so I've added the `DAWN_USE_NEW_TINT_TRANSFORM_API` define which is used by Dawn to know which API to use.
As we're going to have to go through the effort of an API breaking change, use this as an opportunity to rename Transformer to Transform, and remove 'Transform' from each of the transforms themselves (they're already in the transform namespace).

ReplaceAll() registers `replacer` to be called whenever the Clone() method is called with a type that matches (or derives from) the type of the first parameter of `replacer`.
`replacer` must be function-like with the signature: `T* (T*)`, where `T` is a type deriving from CastableBase.
If `replacer` returns a nullptr then Clone() will attempt the next registered replacer function that matches the object type. If no replacers match the object type, or all returned nullptr then Clone() will call `T::Clone()` to clone the object.
Example:
```
// Replace all ast::UintLiterals with the number 42
CloneCtx ctx(mod);
ctx.ReplaceAll([&] (ast::UintLiteral* in) {
return ctx.mod->create<ast::UintLiteral>(ctx.Clone(in->type()), 42);
});
auto* out = ctx.Clone(tree);
```
This is to be used by Transforms that want to replace parts of the AST on clone.

We're seeing some chrome bots fail unittests in ways that suspiciously
look like dynamic casts are doing Wrong Things.
The ClassID::Of() logic depends on the linker folding away duplicate
compilation unit definitions based on ODR rules. If we were to somehow
end up with different definitions, then we'd have two or more different
ClassIDs for the same T type - leading to issues similar to what we're
seeing.
I'm not entirely sure why/how this could happen - and we've so far been
entirely unable to locally reproduce - but it _might_ have something to
do with the goma cache.
In an attempt to work around this, move the static symbol definition out
of a header-local-static and into the .cc file for each of the types.

If there is an issue with the shader, i.e. validation failing, the
former ASSERT_EQs will kill the thread that is running the lambda.
Since the main thread is waiting for a state change, if this assert
kills the thread, the test will hang forever.
This change allows the test to complete and fail correctly in the case
that the test condition fails.
