      Introduce some multi-gpu function helpers and macros. This allows
quickly writing new multiGPU tests for i915 without requiring filters.
There is still drawback of not printing in children logs <g:gpu-number>
for first (for Xe) opened device or for all opened ones (for i915).
I renamed lib from lib/i915/igt_multigpu.* to lib/igt_multigu.* as they
should also work for other vendors.

v2: corrected two patches which introduced multigpu lib (Dominik)
  rebased patch intoducing Xe multigpu macro, corrected description
v3: corrected include in first multigpu patch (Dominik)
  fixed typo (Dominik), refactoring code with Xe and gem macro (Kamil)
v4: corrected typo in macro (Dominik)
v5: removed cached names and relaxing checks for filtered devices
  in 3/8 patch, added Janusz to cc in 1/8...5/8 (Kamil)
v6: extended description of patches 1 and 2, fixed bug in 3/8 (Janusz)
  improved usage of _is_already_opened() (Kamil)
v7: restored prohibition of opening the same card at other index (Janusz)
v8: limit checks for N-th card to 0...N-1 range (Janusz)
 simplify if-else in __search_and_open() (Kamil)
v9: dropped patch 3/8 ("lib/drmtest: allow opening cards in random order")
 as it can be added later, replaced 8/8 ("tests/intel/gem_mmap: add basic
 multi-GPU") with refactor in gem_exec_gttfill (Kamil)
v10: added new helper close function into drmtest.c (Kamil)
 use skip in drm_open_driver() in drmtest.c (Janusz)
 renamed macro from xe_multi_fork_foreach_gpu to multi_fork_foreach_gpu_chip
 and also adding chipset parameter to it, so it is more flexible (Zbigniew)
 fix xe test to use new macro (Kamil)
 squashed patches 3 and 4 into one (Janusz)
v11: moved descriptions for new functions into patch where they are
 introduced (Janusz)
 corrected description in cover letter for v10 (Kamil)
v12: many improvements suggested by Janusz
v13: dropped patch for Xe macro with filtered views as it will be better
 to send it in separate patchset (Janusz)
 other improvements suggested by Janusz
v14: drop multigpu_open_another and replace it with drm_open_driver_another
 in igt_multigpu, add missing igt_require_gem() in gem_exec_gttfill (Janusz)
