Stephen White 05d8b02b0f GLSL: implement host-visible memory padding.
Since GLSL ES does not support the offset= attribute, struct members
with explicit @align or @size attributes require adding explicit
padding members.  This in turn requires rewriting any constructor
calls to initialize the new padding to zero, handled in the same
transform.

Note that this is currently overly-verbose, and will add padding where
GLSL doesn't technically need it (e.g., padding a vec3 out to 16 bytes).

Stephen White 863d9edf59 GLSL: Change Add[Spirv]BlockAttribute to support GLSL
Modify the AddSpirvBlockAttribute transform to fix top-level structure
access of uniform, storage and push-constant buffers for use in the
GLSL backend. The small change to the transform makes the transform
wrap host-sharable buffers, if they're also used as a
non-host-sharable structure. Also rename the transform to
AddBlockAttrbibute in order to reflect its wider applicability.

Ben Clayton 7d34de88f1 tint/test-runner: Split expectations for FXC and DXC
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.

jchen10 ef62b58cf9 Skip Gamma and Gamut conversions for BT.709->SRGB
This introduces a new field 'doYuvToRgbConversionOnly' in
ExternalTextureParams to have the WGSL only do yuv->rgb conversion for
better performance. User studies shows that users don't really care
about the Gamma difference between 2.4 and 2.2.

dan sinclair b29892be09 Update src/tint unittests to new @stage format.
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.
