And remove the WrapArraysInStructs transform.
Wrapping arrays in structures becomes troublesome for `const` arrays, as
currently WGSL does not allow `const` structures.
MSL 2.0+ has a builtin array<> helper, but we're targetting MSL 1.2, so
we have to emit our own. Fortunately, it can be done with a few lines of
templated code.
This produces significantly cleaner output.

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.

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
