1703: Add Rgb9e5Ufloat Format r=kvark a=cwfitzgerald

**Connections**

Addresses part of #967, a wgpu-hal followup to #955.

**Description**

This adds only `Rgb9e5Ufloat`. I removed the explicit numbering from the texture format so we don't have to constantly re-number things. The default numbering is identical to what we were doing.

**Testing**

All backends unconditionally support it, so little testing is needed.

@ -9,6 +9,7 @@
- new `Features::SPIRV_SHADER_PASSTHROUGH` run-time feature allows providing pass-through SPIR-V (orthogonal to the compile feature)
- several bitflag names are renamed to plural: `TextureUsage`, `BufferUsage`, `ColorWrite`.
- renamed `InputStepMode` to `VertexStepMode`
- Implemented `Rgb9e5Ufloat` format.
- Fixed:
- `Device::create_query_set` would return an error when creating exactly `QUERY_SET_MAX_QUERIES` (8192) queries. Now it only returns an error when trying to create *more* than `QUERY_SET_MAX_QUERIES` queries.
