1525: Add Naga bypass to allow feeding raw SPIR-V shader data to the backend. r=kvark a=ElectronicRU
**Connections**
Fixes#1520 .
**Description**
While Naga checking is undoubtedly very useful, it currently lags behind
what is possible in SPIR-V and even what is promised by WGPU (ie binding
arrays). This adds an unsafe method to wgpu::Device to allow feeding
raw SPIR-V data into the backend, and adds a feature flag to request a
backend supporting this operation.
**Testing**
`texture_arrays` example is runnable now, which uncovers an additional bug in Vulkan backend - binding arrays are instead treated like sole bindings, and indices shift, too. Lots of errors from validation layer ensue.

- Remove Cow from wgpu-hal API surface. You graze on in our hearts.
- Rename feature flag to SPIRV_SHADER_PASSTHROUGH in anticipation
of crate feature `spirv` to reduce confusion.
- Add some more documentation about behaviour and intended avenues of
use to the feature.
1528: Support TEXTURE_SPECIFIC_FORMAT_CAPABILITIES for rendertargets. r=kvark a=ElectronicRU
**Description**
With TEXTURE_SPECIFIC_FORMAT_FEATURES enabled, one would assume that render pipeline creation would use extended features
for color/depth-stencil render targets. However, it does not. This aims to fix that discrepancy.

- rename ShaderInput variants
- rename feature flag
- hard error on Metal backend trying to compile SPIR-V
- fix test failing because of feature flag bits changing

1511: Added storage texture array support. r=kvark a=ElectronicRU
**Description**
Arrays of storage images (*f*image*n*D in GLSL parlance) should now be supported.
I also took the liberty to refactor texture format checking a bit,
and tighten up sampled texture support detection for Metal as well.
**Testing**
Not completely sure what's the proper testing approach here, open to suggestions.

1513: Fix failing test compilation on windows - DX12 and DX11 not there. r=kvark a=ElectronicRU
**Description**
Due to some things in macros being left on cfg(windows) and some changed to cfg(dx12/dx11), the tests didn't even compile, much less run.
**Testing**
Ideally, some CI for Windows should be set up.
