DYNAMIC_INDEXING is checked by default, since WGPU doesn't allow
for any kind of specialization constants and constant indexing is
nigh useless.
STORAGE_RESOURCE_BINDING_ARRAY is enabled iff the device supports:
- both or neither of uniform and buffer arrays with dynamic indexing;
- both or neither of sampled and storage images with dynamic indexing.
NONUNIFORM_INDEXING is enabled iff for ALL types of descriptor arrays
*that are supported for dynamic indexing*, nonuniform indexing is
also allowed.
These flags have a limitation in that some platforms
(eg.
https://vulkan.gpuinfo.org/displayreport.php?id=11692#features_core_12)
may support a strange subset of those features (example device
supporting non-uniform indexing for textures and storage buffers,
but NOT for storage textures or uniform buffers). In that case feature
will be reported as missing, even though it is partially present.
In the author's opinion, this flag set is convenient for the
users to query; however, due to aforementioned limitations, it would be
desirable to obtain statistics about "edge-case" platforms and what
percentage of reports they comprise.

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 feature flag

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.
