Alex S 2828100143 Reduce feature flag surface for descriptor arrays.
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.
