ozone: Create GbmBuffers from fourcc formats and gbm flags.

ozone: Create GbmBuffers from fourcc formats and gbm flags.

This CL changes the interface of GbmBuffer to use fourcc formats and
gbm flags instead of gfx::Buffer{Format,Usage}.

In this way we can create modeset buffers that can be mapped and can
be scanned out without the need to add a new gfx::BufferUsage.

No L-G-T-M from a valid reviewer yet. 
CQ run can only be started by full committers or once the patch has
received an L-G-T-M from a full committer.
Even if an L-G-T-M may have been provided, it was from a non-committer,
_not_ a full super star committer.
See http://www.chromium.org/getting-involved/become-a-committer
Note that this has nothing to do with OWNERS files.

CLs for remote refs other than refs/pending/heads/master must contain NOTRY=true
and NOPRESUBMIT=true in order for the CQ to process them
