This allows us to save some work when a bind group is replaced,
although WebGPU still requires us to fail a submission if any
resource in any bind group that was ever referenced during
encoding is destroyed.
Fixes#8399
* Don't remove resources from the usage scope, it is not necessary, and
not useful, since we don't verify the scope is empty afterwards.
* Avoid some unnecessary `unsafe`.
With the only caveat that device creation will now panic if the `wgsl` feature is not enabled, `InstanceFlags::VALIDATION_INDIRECT_CALL` is set and the device supports `DownlevelFlags::INDIRECT_EXECUTION`.
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`
* WIP
* Fix typo
* WIP: Implement structure of command_encoder_transition_resources
* WIP
* More work
* Clippy
* Fix web build
* Use new types for API, more docs
* Add very basic test
* Try to fix test cfg
* Fix merge
* Missed commit
* Use wgt types instead of hal types
* Implement `Clone` for `ShaderModule` (#6939)
* Move to dispatch trait, move more things to wgt
* Move existing code to use new wgt types
* Fixes
* Format import
* Format another file
* Fixes
* Make module private
* Fix imports
* Fix test imports
* Rexport types

This makes the code more straightforward, we were previously holding invalidity state in 2 places: `CommandBuffer::data` could hold `None` and in `CommandEncoderStatus::Error`.
This commit also implements `Drop` for `CommandEncoder` which makes the destruction/reclamation code automatic. We were previously not reclaiming all command encoders (`CommandBufferMutable::destroy` didn't call `release_encoder`) even though all encoders are coming from a pool.
