tools headers UAPI: Update tools's copy of drm/drm.h header 

Picking the changes from:

  2e290c8d8d ("drm: document minimum kernel version for DRM_CLIENT_CAP_*")
  bbf4627ba6 ("drm: clarify and linkify DRM_CLIENT_CAP_WRITEBACK_CONNECTORS docs")
  88938bf343 ("drm: reference mode flags in DRM_CLIENT_CAP_* docs")

Silencing these perf build warnings:

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

No changes in tooling as these are just C comment documentation changes.
