Dependencies on `std` that still exist:
* Locks
* `std::error::Error` (waiting for Rust 1.81)
* `std::os::raw::c_char` for FFI
* `thread_local` and `Backtrace` in `snatch`
If `debug_assertions` or the `"validate-locks"` feature are enabled,
change `wgpu-core` to use a wrapper around `parking_lot::Mutex` that
checks for potential deadlocks.
At the moment, `wgpu-core` does contain deadlocks, so the ranking in
the `lock::rank` module is incomplete, in the interests of keeping it
acyclic. #5572 tracks the work needed to complete the ranking.
Move the `Mutex` in `Device::command_allocator` inside the
`CommandAllocator` type itself, allowing it to be passed by shared
reference instead of mutable reference.
Passing `CommandAllocator` to functions like
`PendingWrites::post_submit` by mutable reference requires the caller
to acquire and hold the mutex for the entire time the callee runs, but
`CommandAllocator` is just a recycling pool, with very simple
invariants; there's no reason to hold the lock for a long time.
1403: Trace render passes before they are ran r=cwfitzgerald a=kvark
**Connections**
Follow-up to #1245
**Description**
We want the API traces to reproduce issues. Previously, we moved all the resource creation to happen after the trace is written.
This PR follow-up by also recording the render pass commands even in the case where one of them triggers a validation error.
Another big part of the PR now is handling the command buffers that failed for some reason. The submission is skipping them now instead of erroring the whole thing.
**Testing**
Tested manually on wgpu-rs examples

* Add command buffer fill buffer method
* Added test for buffer fill
* Added image clear + test
* image/buffer clear methods are now pure clear to zero
* fix cargo clippy & int type issues
* clear buffer alignment is now given by COPY_BUFFER_ALIGNMENT
* joined buffer/image clear player tests
* ImageSubresourceRange is now used in TextureViewDescriptor
- Clean up after the pending writes on destroy.
- Fix temporary buffer creation.
- Fix internal thread initialization by the command allocator.
- Clean up player event_loop usage.
