tests/gem_render_copy: Add media compression subtests

Add subtests using the vebox copy function to test the blit
functionality involving media compressed source and destination buffers.

These cover all the source and destination tiling formats supported by
the vebox engine and validate the buffer sharing between the render and
vebox engine (a render compressed buffer used by the vebox engine and a
media compressed buffer used by the render engine).

v2:
- Rebase on latest igt.
  Simplify the condition for enabling media compression in the surface
  state.
