The changes in this patch stack will change how IPDL generated files are built,
such that these issues are now surfaced, especially during non-unified builds.

This patch removes more main thread dependencies from the content side
of WebGPU. Instead of issuing a resource update for an external image,
we now use an async image pipeline in conjunction with
CompositableInProcessManager from part 1. This allows us to update the
HTMLCanvasElement bound to the WebGPU device without having to go
through the main thread, or even the content process after the swap
chain update / readback has been requested.

This patch ensures that we only update the external image resource for
WebGPU when there has been an actual change for the resource. In order
to guarantee this, we wait for the present to complete, and only then
issue the update. WebRenderBridgeChild::SendResourceUpdates will also
trigger a frame generation if any resources were changed, which means we
don't need to trigger a paint on the frame itself anymore.
Note that we still have a race condition when we write into the
MemoryTextureHost while in PresentCallback, and the renderer thread may
be accessing the pixel data to upload to the GPU.

Similar to PWebGL, we want PCanvasManager to manage the PWebGPU
protocol. This will allow us to reuse the machinery that works for both
the main thread, and arbitrary worker threads to create PWebGPU
protocols.
For now, the only owner is still the main thread, so it should work very
similarly as to how it does with PCompositorBridge.
This patch also introduces some quality of life changes, such as making
the protocol ref-counted, and avoiding respinning the wheel for
CanSend() for IPDL actors.

we were doing UTF16 -> ASCII null term -> UTF8, and we were losing information on the way.
Now we go UTF16 -> UTF8 -> UTF8 null term
Also, we no longer accept SPIR-V

This update makes wgpu a vendored dependency instead of having it in gfx/wgpu.
## Notes
It relies on https://phabricator.services.mozilla.com/D123157
It has a quirk related to OpenGL ES backend. Previousy, we manually had to disable GL backend
in order to avoid vendoring WASM dependencies in. This time, manual editing is more complicated,
so instead this change adds a few cargo patch lines to point WASM dependencies to dummy projects.
The update also totally removes SPIRV-Cross, since the latest `wgpu` doesn't depend on it any more.
The compiled binary size for Gecko should improve with this.

This *mostly* gets us the latest WebIDL API of WebGPU. There is a few limits we are missing, and maybe some things I didn't notice.
But it gets us the new `GPUCanvasContext`, `GPUSupportedLimits`, and `GPUVertexStepMode`.

When the pipeline layout is implicit at pipeline creation,
we collect the IDs of BGLs, to be able to produce GPUBindGroupLayout
object upon user request. However, the produced object didn't know if
it owns the ID or borrows it, so it would issue a "drop" when going out of scope.
This change establishes this distinction. In addition, it gets the Pipeline Layout ID,
and together with the BGL ids, they are sent to GPU process upon pipeline destruction.
When the GPU process is done with these IDs used, it will kick back a message to the
Content process, allowing the IDs to be reclaimed.

We are now passing an extra flag on Unmap to keep the shmem around.
Previously, we'd be freeing the Shmem accidentally on buffers that are writable and mapped at creation.
We also add a bit of logging on the WebGPUParent side.

Updates wgpu, WebGPU IDL, in particular the ImageCopyXxx types and render pass attachments.
Adds explicit mapping of the GPUTextureFormat enum. Our old casting was incorrect, because the enums diverged a bit.

This is another WebGPU API update, it picks up a lot of changes that were made recently:
- new bind group layout
- new render pipeline descriptor
- new vertex formats
- limits
- compressed texture formats
- index format
- query sets
- and more small ones!
It also brings in the updated `gfx/wgpu` to support these API changes.
