Also fixes `Deno.privateCustomInspect`, which was defined as static
methods of the classes and was not working properly.
(cherry picked from denoland/deno#28650)
Previously, the check was skipped if the copy was a single row, which is
not correct. The check should be made whenever bytes_per_row is
specified. It is permissible not to specify bytes_per_row if the copy is
a single row, but if it is specified, it must be aligned.
Also removes a redundant check of the `offset` alignment.
Since the offset and bytesPerRow alignment checks are not part of
"validating linear texture data", I chose to remove that instance of
them. These checks are now in `validate_texture_buffer_copy`, which
does not correspond 1:1 with the spec, but has a comment explaining how
it does correspond.

We were not implementing this check of effective buffer binding size.
Check that it's a multiple of 4, including
`webgpu:api,validation,createBindGroup:buffer,effective_buffer_binding_size:*`
that this is now implemented as intended.
* Restore allowance of unaligned buffer-texture copies
This fixes a regression introduced by #7948. However, it makes it
possible to reach a panic in initialize_buffer_memory if the copy
requires initializing a region of memory that is not 4B aligned.
* Fix CopyT2T of multi-layer depth/stencil textures
* Adjust test list
* Additional validation of buffer-texture copies
Fixes#7936, but leaves a TODO for #7947
* Skip tests failing on dx12
* Update comments and change unwrap_or to expect
* Additional validation of texture copies
* Copies must not overlap.
* Copies of multisampled or depth/stencil formats must span
the entire texture.
* Move no-op for zero-size copies after parameter validation.
Closes#2951Fixes#7844
* Fix issue with combined depth+stencil copy on dx12
* PR feedback
