sys-kernel/linux-headers: move non-upstream VP9 headers to their own file
These controls are not in mainline and we will introduce the actual
upstream controls once they are stabilized. In order to prepare for
this, move the old controls to their own file, which we include from
v4l2-controls.h to make sure client behavior is not disturbed.
Also remove vp9-specific pointer unions and control type enums, which
are not upstream and not used by Chromium.
