WGSL states that `f32` is a IEEE-754 binary32. mediump precision guarantees are much smaller than highp, and using mediump can break code generated by tint.

... overloads for texture cube arrays
FXC is telling porkies, when it says "The array element count
of GetDimensions on TextureCubeArray objects is unavailable
on ps_5_1".
The actual issue, as identified by Teodor Tanasoaia at Mozilla,
is that the argument needs to be unsigned.
In fact, *all* the texture queries should have used an unsigned
scalar or vector for the output value. This has been broken
forever!
This reverts commit bd9f6e6684.

It appears that FXC and DXC do some validation post dead-code-elimination.
These tests have been updated so that the return value is assigned to a storage buffer, ensuring that all validation is performed.
Many DXC tests are affected by https://github.com/microsoft/DirectXShaderCompiler/issues/5082, which have been SKIP'ed.

Polyfill this for the SPIR-V, HLSL and GLSL backends by replacing bgra8unorm with rgba8unorm, and swizzling.

To match the spec.
Also add a bunch of missing texture test cases to
src/tint/ast/builtin_texture_helper_test.cc. Fix all the tests that were
broken because these were not being exercised.

Change tint's `--fxc` flag to take the path of the FXC compiler DLL.
Have tint attempt to validate with both FXC and DXC if `--validate` is
passed.
Fix the 'dirsWithNoPassExpectations' logic which looks like it got
broken with the tint -> dawn merge. It also incorrectly applied
filepath.FromSlash() on windows.

This CL updates all of the Tint unittests to the new @stage shorter
syntax. This also updates the WGSL writer to emit the new short forms
instead of using the deprecated form.
