tests: pimp tiled_after_untiled_blt

Browse Source 
Now with more tiling transition tests. Changes:
- refactoring to reuse the tiling transition functions.
- add a tiled->untiled transition
- add a tiled->tiled transition with different stride
- add a check at the end to ensure that the tiling has indeed changed
  on the test_bo

/** @file gem_tiled_after_untiled_blt.c
*
* Testcase: Check for proper synchronization when switching tiled->untiled
* Testcase: Check for proper synchronization when switching untiled->tiled
*
* The blitter on gen3 and earlier needs properly set up fences. Which also
* means that for untiled blits we may not set up a fence before that blt has
