The OpenGL ES 3.1 spec says:
"The point size is taken from the shader built-in gl_PointSize written by the vertex shader, and clamped to the implementation-dependent point size range. If the value written to gl_PointSize is less than or equal to zero, or if no value is written, the point size is undefined."
ANGLE/D3D11 will emit a warning on this and abort processing, causing dawn_end2end tests to fail.

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.

Note: ES doesn't support cube arrays, so this fixes the tests but does
not cause them to pass.

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

This change essentially relands 10c554ecf4,
aka https://dawn-review.googlesource.com/c/tint/+/82140.
(Somehow, I managed to revert most of that in the subsequent CL for
reverseBits. I suspect a bad upstream and/or rebase.)

The multiplanar external texture transform has been integrated into
Dawn, which means we have no use for the single plane transform - so it
should be deleted.
