On GLES B8G8R8A8_SRGB is not available and B8G8R8A8_UNORM can not be
created as immutable. In order to have versions of these formats that
can be created immutable on GLES provide the formats R8G8B8A8_SRGB and
_UNORM with swizzling to BGRA that can then be used instead of the BGRA
formats. Since this may break things these swizzled versions will later
be only enabled when the guest requests them.

The function emit_sampler_decl() considers that GLES does not have 1D
textures, but it ignores the fact that we can have a range passed into
the function.
This workaround predates the correct fix in vrend_shader_samplertypeconv()
which returns a "2D" literal as needed.
Drop this partial workaround.

Transfer strides are either set internally or coming from
virgl_renderer_transfer_{write,read}_iov. As far as I can tell,
Mesa always passes sane values. We also expect sane values in
places like vrend_renderer_transfer_write_iov,
vrend_transfer_send_readpixels, and vrend_transfer_send_getteximage
already. Let's reject bad strides.
This fixes, for example, transfers to 1D array (thus box->height is
1) with non-default stride.

This commit improves bound checking by more accurately calculating
the expected transfer size. This improvement is achieved in two ways:
1. Using the image level (layer_)stride when the (layer_)stride is 0,
which matches the interpretation we use for performing the actual
read/write.
2. Calculating the transfer size by using the exact end offset in
the image, instead of using multiples of whole image rows.
The increased accuracy increases safety, and also allows us to support
some transfers with explicit strides that were previously rejected (see
added test).
