Skeleton surface interfaces in cc/surfaces

Skeleton surface interfaces in cc/surfaces

This adds a very basic surface class with tests under cc/surfaces
to establish gyp and DEPS rules. While this system is under early
development it shouldn't be used by anything outside of unit tests.

The idea here is to start landing the surface implementation code in
cc/surfaces/ but try to avoid having production code depend on it before it's
ready.  Thus, this lives as a separate library with DEPS rules constructed to
restrict it to unit tests for now.  As it gets further along we'll relax these
rules.  As this implementation lives in cc/ and a number of systems can depend
on the compositor, this means adding an explicit DEPS exclusion for the
directory for now.  This is a bit.

I've also added a cc/surfaces/OWNERS file which is completely redundant (since
i'm in cc/OWNERS) but will hopefully help direct questions/etc in the right
direction.  I expect this file to grow as more people work on the implementation
and eventually move when the rest of this implementation is ready to move,
probably to somewhere where the OWNERS list won't be redundant with cc/OWNERS.

Ben - please give top-level approval for DEPS changes.  I've cc'd OWNERS on the
rest as an FYI
Enne - please review
