1510: OpenGL ES3 backend r=cwfitzgerald,Gordon-F,kvark a=kvark

**Connections**
Follow-up to #1471

**Description**
The new wgpu-hal backend for GLES3 ~~and WebGL2~~
Edit: WebGL2 is not included here

**Testing**
Examples!

Current status:
  - all examples work, minus the next issue
  - "mipmap" is buggy because we don't have a good way to do mipmap/layer selection
  - automated testing?

1576: Switch all bitflag names to plural r=cwfitzgerald a=kvark

**Connections**
#1471 added a lot of singular bitflag names. Previously, we weren't really consistent.

**Description**
This PR changes all of the names to be plural, except for a few that don't imply singularity, and are matching WebGPU upstream. Maybe we need to convert them too?

**Testing**
self-tested

1602: New DX12 backend (unfinished) r=kvark a=kvark

**Connections**
Continuation of #1471

**Description**
Mostly fresh implementation on DX12 backend for wgpu-hal
Core changes:
  - texture usage is filtered before passing to `create_texture_view`, so that wgpu-hal can assume every bit is important.
  - all the copies involving textures are limited to one array layer at a time
  - remove render pass boundary usages

**Testing**
Examples (not running yet)

Operations like `OpUGreaterThan` accept arguments as long as they are integers
(signedness doesn't matter) but they must be interpreted as `Uint`s.
