Check that raw buffers and raw bind groups are valid #4895

Another step towards #4787.
Rebased on top of #4894.

Description

This addresses a lot of wgpu-core's code which assumes that the raw buffer is always accessible (Buffer::raw(guard) was unconditionally unwrapping the buffer), and instead returns an error when this is not the case.

In addition, accessing a raw bind group now requires checking that the underlying raw buffers are also accessible.

Checklist

Run cargo fmt.
Run cargo clippy.
Run cargo xtask test to run tests.

These are only written to clear the vectors when triaging bindgroups for destruction, which is not necessary. We can let the reference counts drop when the bind group is dropped.

This commit removes most of the unconditional unwrapping of raw buffers. If the raw buffer was snatched, gracefully return an error. The exception is for staging buffers which are still unwrapped, which we should tackle in a followup.

Remove some locks in BindGroup

These are only written to clear the vectors when triaging bindgroups for destruction, which is not necessary. We can let the reference counts drop when the bind group is dropped.
