tools headers UAPI: Sync the i915_drm.h with the kernel sources

Picking the changes from:

  1cc064dce4ed0ff1 ("drm/i915/perf: Add support for OA media units")
  c61d04c9eb435498 ("drm/i915/perf: Add engine class instance parameters to perf")
  02abecdeebfcd384 ("drm/i915/uapi: Replace fake flex-array with flexible-array member")

Silencing these perf build warnings:

  Warning: Kernel ABI header at 'tools/include/uapi/drm/i915_drm.h' differs from latest version at 'include/uapi/drm/i915_drm.h'
