1077: Remove extern "C" from set_index_buffer r=kvark a=DevOrc
**Connections**
Fixes an issue that is blocking gfx-rs/wgpu-native#61
**Description**
Moves the ffi definition of wgpu_render_bundle_set_index_buffer / wgpu_render_pass_set_index_buffer to wgpu-native. This is needed because wgpu-native has its own version of IndexFormat that is different than the wgpu_types version.
**Testing**
My projects with wgpu-native work

The purpose of the PR is to support Naga modules everywhere.
As a requirement, it updates the gfx-rs version used.
Most of the logic is dedicated towards building a shader interface,
where previously we just used naga's IR. Now we have our own mini-IR.
966: Immediate resource destruction and freeing r=cwfitzgerald a=kvark
**Connections**
Fixes#964
**Description**
We are making it so a buffer or a texture can have their native resources freed while they are still referenced, so without waiting for GC.
In addition, the PR adds a few missing cases where error IDs should have been handled, like at render pass encoding.
**Testing**
Tested on wgpu-rs examples, see https://github.com/gfx-rs/wgpu-rs/pull/591

* Pass [u8] instead of [u32] for push constants
Use 2-instruction aligner
Fixed alignment
Fixed offsets
Added alignment checks and fixed size
Use semantic constants
* Replaced all magic number with constant
* Fixed type cast
* Allow copying from depth textures
* Rename TextureFormat::is_depth_format to just is_depth
* Only allow Depth32Float format for copying, and only as source
895: Improve validation in B2B copies and RenderCommands r=kvark a=kunalmohan
**Connections**
_Link to the issues addressed by this PR, or dependent PRs in other repositories_
**Description**
_Describe what problem this is solving, and how it's solved._
Validation for the following have been added-
- Validate all parameters in B2B copy even if `copy_size == 0`.
- Check for copy operations issued within same buffer.
- `RenderPass.setViewport()`
- `RenderPass.setScissorRect()`
**Testing**
_Explain how this change is tested._
Tested with CTS in Servo. More tests pass now. Will test on wgpu-rs now.
<!--
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.
