When the host is gles >= 3.2, gl >= 4.3, or when the extension
GL_(ARB|EXT|OES)_copy_image is available, memcopy like blitting and region
copying can be done for many color format combinations by using
glCopyImageSubData.
This fixes a number of tests from the subset
dEQP-GLES31.functional.copy_image.non_compressed.viewclass_*
v2: - Clean list of canonical formats (Gurchetan Singh)
- Use size of canonical formats to decide whether they can be copied via
gCopyImageSubData
- Also honour the render state when deciding whether glCopyImageSubData
will do, or whether we need to do a blit.
v3: - replace format size check by compatibility check (Gurchetan Singh) but
keep the check seperate because we need to add logic for compressed
texture later
