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

With this change, the backend sanitizers always run the
MultiplanarExternalTexture transform. If the new option is enabled, it
auto-generates bindings for this transform.
This change also enables this auto-generation for the Tint commandline
application, as well as for the fuzzers.

Textures as function parameters should not have the "uniform"
qualifier. Fixed by handling StorageClass::kUniformConstant the
same as StorageClass::kUniform, and removing the unconditional
"uniform" qualifier output. (Global texture variables have
StorageClass::kUniformConstant set, while function parameters don't.)

This transform converts compound assignment statements into regular
assignments, hoisting LHS expressions and converting for-loops and
else-if statements if necessary.
The vector-component case needs particular care, as we cannot take the
address of a vector component. We need to capture a pointer to the
whole vector and also the component index expression:
// Before
vector_array[foo()][bar()] *= 2.0;
// After:
let _vec = &vector_array[foo()];
let _idx = bar();
(*_vec)[_idx] = (*_vec)[_idx] * 2.0;

Reuse the logic for resolving binary operator result types that was
implemented for binary expressions. This validates that the LHS and
RHS are compatible for the target operator. We then try to match the
resolved result type against the LHS store type.

Implement new transform UnwindDiscardFunctions that replaces discard
statements with setting a module-level bool, adds a check and return for
this bool after every function call that may discard, and finally
invokes a single function that executes a discard from top-level
functions.
Regenerated tests and remove HLSL ones that used to fail FXC because it
had difficulty with discard.

We still use the StrideAttribute AST node in the SPIR-V reader for
strided arrays and matrices, which are then removed by transforms.
The WGSL parser no longer has to handle attributes on types.

Since this was the only attribute allowed on structures, we can also
remove the parsing code for them. However, we still need to have
attributes on the struct AST node, since the AddSpirvBlockAttribute

This transform ensures that expressions are evaluated in the order
defined in the WGSL spec. It does this by making sure to hoist
expressions that have side-effects (calls) along with variables that may
receive these side-effects to lets in the correct order.

In GLSL, runtime-sized arrays are only valid in interface blocks, not
in structs. The existing code was attempting to avoid emitting structs
containing runtime-sized arrays but was confused by type aliases in
the AST resulting in arrays being missed.
The fix is to do the work on the semantic types instead, where type
aliases have been resolved.

Unlike other texture functions in GLSL, textureGather() and
textureGatherOffset() do not expect the refZ value to be appended to
the texture coordinates. It is passed as a regular argument. So append
refZ to coordinates by default, and pass as a regular parameter only
for the gather functions.

Multiple bugs here:
1) Like texture(), GLSL's textureLod() on depth textures returns a
scalar, and does not need to be swizzled. So set glsl_ret_width to
1 in that case.
2) Like texture(), GLSL's textureLod() always requires a Dref
parameter, so append a zero if not present.
3) GLSL's "lod" parameter to textureLod() is always a float, unlike
WGSL's textureSampleLevel() which is an i32 for depth textures,
so cast it.
Along the way, I discovered that textureLod() is not supported on
samplerCubeShadow or sampler2DArrayShadow (even on Desktop GL). So some
tests will never pass. Logged as https://crbug.com/dawn/1313
