877: Add image cube array feature. r=kvark a=StarArawn

**Connections**
None

**Description**
Enable `IMAGE_CUBE_ARRAY` in vulkan and dx12. Note: Currently this will cause metal to break as the `available_features` from the physical device will never include `IMAGE_CUBE_ARRAY`. Thus I'm opening this as a draft until gfx-hal metal can check and pass the feature on.

**Testing**
<!--
Non-trivial functional changes would need to be tested through:
  - [wgpu-rs](https://github.com/gfx-rs/wgpu-rs) - test the examples.
  - [wgpu-native](https://github.com/gfx-rs/wgpu-native/) - check the generated C header for sanity.

Ideally, a PR needs to link to the draft PRs in these projects with relevant modifications.
See https://github.com/gfx-rs/wgpu/pull/666 for an example.
If you can add a unit/integration test here in `wgpu`, that would be best.
-->
I can test this with my repo using wgpu-rs here which uses cube arrays:
