It seems that where it was, it warned about the context being recreated
in every case, no matter whether the context would actually be recreated
or not.
- 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.

wgpu currently checks if the `write_mask` is 0 to determine wether a
stencil is used as readonly or not. However Webgpu contains a more
complex ruleset that also checks the cull mode and face operations to
determine if the stencil is readonly or not.
This commit brings these new rules to wgpu.
