OpenGL: Support B2T and T2T copies with BC formats
This patch implements the creation, buffer-to-texture copies and
texture-to-texture copies with BC formats on OpenGL backend. Note that
OpenGL SPEC also has the same issue about texture-to-texture copies
with compressed textures as Vulkan SPEC, so we have to skip the related
case.
The texture-to-buffer copies with BC formats and related end2end tests
will be supported in the following patches.
