* [spirv-out] Fix adding illegal decorators on fragment outputs.
Furthermore, fix allowing to add `Centroid` and `Sample` decorator to vertex inputs.
Fixes#2270
* Add test for fragment outputs
* Fix fragment-output.wgsl test using more than 8 outputs in a single shader
Breaks HLSL & MSL validation
* formatting
The existing `per_stage_map` field of MSL backend options specifies
resource binding maps that apply to all entry points of each stage type.
It is useful to have the ability to provide a separate binding index map
for each entry point, especially when the same shader module defines
multiple entry points of the same stage kind.
This patch replaces `per_stage_map` with a new `per_entry_point_map`
option where resources are keyed by the entry-point function name.
Use the local (not global) invocation id to decide which invocation should do the initialization, so that every workgroup gets initialized, not just the first.
arrays can be put behind pointers in inout and out parameters in GLSL and HLSL,
whose dimensions must be specified to let array access
compile. so, we specify their dimensions.
fixes#2248
- 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.

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.

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.
According to https://registry.khronos.org/OpenGL/specs/es/3.2/GLSL_ES_Specification_3.20.html#built-in-language-variables
> The variable gl_PointSize is intended for a shader to write the size of the point to be rasterized. It is measured in pixels. If gl_PointSize is not written to, its value is undefined in subsequent pipe stages.

The handle dependency validation code was using the handle's index
directly while trying to erase the handle type. This would cause the
validator to crash while processing the first handle of the arena since
it would be trying to construct a `NonZeroU32` with a zero.
This commit fixes the issue by adding 1 to the index which not only
fixes this panic but also makes so that the created Handle is equal to
the passed handle (minus the type that was erased)
It also fixes the error message not including the subject's kind
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`.
