Subject: [PATCH] Enable VAVDA, VAVEA and VAJDA on linux with VAAPI only

This patch contains all the changes necessary to use VA-API along with
vaapi-driver to run all media use cases supported with hardware acceleration.

It is intended to remain as experimental accessible from chrome://flags on linux.
It requires libva/intel-vaapi-driver to be installed on the system path where
chrome is executed.  Other drivers could be tested if available. Flags are
kept independent for linux, where this feature has to be enabled before
actually using it.  This should not change how other OSes use the flags
already, the new flags will show at the buttom on the section of unavailable
experiments

The changes cover a range of compiler pre-processor flags to enable the stack.
It moves the presandbox operations to the vaapi_wrapper class as the hook function
is available there. vaInit will open driver on the correct installed folder.

chrome flags consolidtation into only two flags for linux.  Mjpeg and accelerated
video are used.  The other flags are kept for ChromeOS and other OSes.

Developer testing was made on skylake hardware, ChromeOS and Ubuntu.

BUG=NONE
TEST=subjective testing with VAVDA,VAVEA and VAJDA, autotest for encoder
     and decoder hardware accelerated
     have libva/intel-vaapi-driver installed and not installed in the system
     repeat on different hardware families
