[igt-dev] [PATCH i-g-t v3 0/8] Update gem_blits for newer generations

[Karolina Stolarek <karolina.stolarek@intel.com>]

gem_blits test utilizes XY_SRC_COPY_BLT, a legacy blitter command
that is not available on newer generations such as MTL. To make
sure the test covers such platforms, update it to switch to
XY_FAST_COPY_BLT for blit copy operations.

In addition to this change, the series:
  1) Adds helpers to i915_blt library that check support for
     XY_SRC_COPY_BLT command and its capabilities
  2) Updates the definitions of older platforms to properly list
     all available commands and tilings
  3) Updates gem_blits to use aforementioned helpers to detect
     tiling formats supported by the platform

v3:
  - Rebase the changes, as they stopped applying cleanly
  - Add static asserts on tiling enums, to make sure that changing
    defines or blt_tiling_type results in a compiler error
  - Reorder T_YFMAJOR value to it directly follows Tile4. Thanks to
    __block_tiling() and __fast_tiling() switches, this change
    shouldn't break gem_ccs/gem_exercise_blt tests

v2:
  - Remove libdrm include in "tests/i915/gem_blits: Add XY_FAST_COPY_BLT
    support for gem_blits". It's not needed and causes compile errors
    on some targets
