VAAPI Wrapper: refactor management of drm file
Make sure we use the same file in all instances of VaapiWrapper.
Define a refcounted global instance of VADisplayState that is only initialized
(via vaInitialize()) once and destroyed upon release of the last refcount.
This ensures a single drm_intel_bufmgr per fd, and avoids the double-close
problem as seen in bug 464628.
Pipe a PreSandboxInitialization to open the render node before starting sandbox.
After this CL the VEA/VDA unittests need to invoke the PreSandboxInitialization
as well.
BUG=475250
TEST=verify HW video works on link (check histograms) and VDA/VEA unittests
