Move builtin_to_string() and builtin_type() to
the CanonicalizeEntryPointIO transform. Use the former to
rename entry point IO variables to the gl_ names, and the latter
to cast values to the correct type.

More line() and less std::endl.
More automated indents and less manual spacing.
Put a single newline after every struct and function declaration.
Note that this does touch every test result, but only affects whitespace.

FXC fails to compile code that assigns to dynamically-indexed fixed-size
arrays in structs on internal shader variables with:
error X3500: array reference cannot be used as an l-value; not natively
addressable
This CL detects this case, and transforms such assignments into copying
out the array to a local variable, assigning to that local, and then
copying the array back.
Also manually regenerate SKIPs for HLSL/FXC after this change, which
fixes 30 tests. Also exposes some "compilation aborted unexpectedly" now
that "array reference cannot be used as an l-value" has been fixed. For
tests that fail for both DXC and FXC, updating SKIPs to the DXC one to
help distinguish actual FXC bugs from valid errors.

It seems we haven't run our e2e tests with FXC validation in a long time
- at least not since we've added the vk-gl-cts corpus.
Locally disabled exclusion of "/test/vk-gl-cts/" in test-runner/main.go,
and ran:
./test/test-all.sh out/build/x64-Debug/tint.exe --format hlsl --fxc --generate-skip
These will need to be manually removed once the skips aren't needed by
deleting them all, and re-running as above.

For these tests, we only really care that we can successfully consume
them and generate valid output for each backend. Having the expected
files in the tree generates significant churn for any change to how we
generate backend code, which makes it hard to inspect diffs.

The refactored CanonicalizeEntryPointIO transform makes it much easier
to handle SPIR-V style IO as well, and doing this removes a lot of
duplicated code. Remove all of the SPIR-V transform code for shader IO
and vertex point size.

This is a major reworking of this transform. The old transform code
was getting unwieldy, with part of the complication coming from the
handling of multiple return statements. By generating a wrapper
function instead, we can avoid a lot of this complexity.
The original entry point function is stripped of all shader IO
attributes (as well as `stage` and `workgroup_size`), but the body is
left unmodified. A new entry point wrapper function is introduced
which calls the original function, packing/unpacking the shader inputs
as necessary, and propagates the result to the corresponding shader
outputs.
The new code has been refactored to use a state object with the
different parts of the transform split into separate functions, which
makes it much more manageable.

This reverts commit e5dbe24e94.
Reason for revert: Makes the Tint-Dawn roll fails because of
MSL compilation errors on as_type<uint>(-2147483648):
as_type cast from 'long' to 'uint' (aka 'unsigned int') is not allowed
as_type<uint>(-2147483647) compiles fine, so this is most
likely because the MSL compiler types the literal as a long
(since without the - it is larger than the max int32).

This adds SPIR-V assembly and WGSL tests derived from VK-GL-CTS commit
571256871c2e2f03995373e1e4a02958d8cd8cf5. The following procedure was
followed:
- Those .amber files in VK-GL-CTS wholly owned by Google were
identified
- All GLSL and SPIR-V shaders were extracted from the Amber files and
converted into SPIR-V binaries
- The compact-ids pass of spirv-opt was applied to each binary
- Duplicate binaries were removed
- spirv-opt -O was used to obtain an optimized version of each remaining
binary, with duplicates discarded
- Binaries that failed validation using spirv-val with target
environment SPIR-V 1.3 were discarded
- Those binaries that tint could not successfully convert into WGSL were
put aside for further investigation
- SPIR-V assembly versions of the remaining binaries are included in
this CL
- test-runner with -generate-expected and -generate-skip was used to
generate expected .spvasm, .msl, .hlsl and .wgsl outputs for these
SPIR-V assembly tests
- Each successfully-generated .expected.wgsl is included in this CL
again, as a WGLSL test
- test-runner with -generate-expected and -generate-skip was used again,
to generate expected outputs for these WGSL tests
