* Have `prepare_staging_buffer` take a raw hal Device. This helps the borrow checker understand that we can borrow `pending_writes`'s encoder and the raw Device at the same time. * Always free staging buffers. We must ensure that the staging buffer is not leaked when an error occurs, so allocate it as late as possible, and free it explicitly when those fallible operations we can't move it past go awry. Fixes #2959. * Some tests for texture and buffer copies. * Add CHANGELOG.md entry.
