1ad47f732d Fix texture built-ins where u32 was expected (#2245) 
- The Typifier was updated to expect `uint`
- Both `glsl` and `spv` frontends where updated to cast the result to `sint`.
- Both `glsl` and `spv` backends where updated to cast the result to `uint`.
- Remove cast in `msl` backend.

0a2e93c098 glsl-in: Perform output parameters implicit casts 
Glsl defines under `Function Definitions` (Paragraph 6.1 in glsl 4.60),
the following:

> When function calls are resolved, an exact type match for all
> the arguments is sought.
> (...)
> If no exact match is found, then the implicit conversions in
> section “Implicit Conversions” will be applied to find a match.
> (...)
> Mismatched types on output parameters (out or inout) must have a
> conversion from the formal parameter type to the calling argument type.

The glsl frontend wasn't performing this implicit cast for output parameters.

This commit fixes that by using a proxy write, this
creates a spill variable with the correct type and in the call
prologue a conversion is made back to the original type and the
value is stored in the original variable.

fc81a20f53 spv-in: Don't apply interpolation to fragment shaders outputs (#2239) 
SPIR-V doesn't allow the `Flat`, `NoPerspective`, `Sample` or
`Centroid` decorations on fragment shaders outputs, but the spirv
frontend was applying default interpolation to all outputs
unconditionally.

This wasn't an issue for most shaders since they output floats and the
default values for them don't interfere with SPIR-V semantics, but if
the shader returned a uint or int the interpolation would be set to
`Flat` which as stated above is disallowed.

This commit fixes the issue by only running the default interpolation
code when constructing the entry point and if the stage/IO allow it.

67ea8f0c06 [wgsl-in] Split into multiple files (#2207) 
Make changes suggested in #2075, but put off to a separate PR because they would interfere with reviewing the change:

- Split the new WGSL front end into modules in a logical way.
- Rename `Parser` to `Frontend`.
