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.
v2: Don't leak fbo's
