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.
TransferError now has separate variants for texture copy formats that
are only forbidden in combination with specific aspects
(CopyFrom/ToForbiddenTextureFormatAspect), and texture copy formats that
are always forbidden, irrespective of the aspect
(CopyFrom/ToForbiddenTextureFormat).
This produces a less confusing error message by not mentioning the
aspect it is not relevant.
Although the operation of these functions is defined in terms of f16
semantics, the input/output types are not f16, and they are generally
available even when native `f16` support is not. But in at least one
case, they are only available with `f16` support, so add a new downlevel
flag that is cleared when these functions are not available.
Add some infrastructure to simplify testing of missing
capabilities/extensions, and add tests for a few more kinds of f16
usage.

It makes sense for a function to be `FnMut + Send`, or `Fn + Send + Sync`,
but not `Fn + Send` because that is overly restrictive for the caller and
the callee.

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.
