lib/rendercopy/tgl: Add support for gem_render_* tests on TGL

Previous generations didn't use SWSB dependency tracking.
For that reason shader was adopted to handle that on TGL.

FIXME: Some tests still have to be fixed, currently working:
      gem_render_copy @linear @x-tiled @y-tiled @yf-tiled
      gem_render_copy_redux
      gem_render_linear_blits @basic
      gem_render_tiled_blits @basic
