mesa/meta: Add a partial implementation of CopyImageSubData

This provides an implementation of CopyImageSubData that works if both
textures are uncompressed.  This implementation works by using a
combination of texture views and BlitFramebuffer.  If one of the textures
is compressed, it returns false and the driver is expected to provide a
fallback.
