Add some missing unit tests and update cc_unittests and webkit_compositor_bindings_unittests

Add some missing unit tests and update cc_unittests and webkit_compositor_bindings_unittests

After GTFO, some unit test files were not in the right place, or missing
entirely.  This patch (1) adds some missing unit tests, (2) moves some tests
from webkit_compositor_bindings_unitttests to cc_unitttests, and (3) removes
some redundant entries in the gyp files for those targets.

First few try attempts, the path was moving several files from
webkit/compositor_bindings/ to cc/.   I don't yet know how to work around this.

The second patch set I tried to keep LayerChromium.cpp in the old location, but
it still failed to apply the patch on that file because it couldn't be found.

Looks like you've been bitten by my WebCore => cc namespace change.

I think this is the patch that will probably pass all try bots. =)

I think this patch might be a little time-sensitive, since its a manual file
move baked into the patch.  (this was the workaround for getting the patch to
work on the try bots).

Whenever this lands, I can double-check afterwards that the move did not skip
any new tests that anyone else added while this was in flight.

Thanks for review -- as long as you guys are OK with probably loosing the svn
revision history for the moved files, can we put this in the commit queue now? 
Thanks in advance.

Fine with me - the real history is all in WebKit.

Originally the tree was red and errors were unrelated.  Then,
http://codereview.chromium.org/10917251 landed and the unit test was not updated
since it was not there =)

James, can you please double-check that the changes I made to
CCRendererGLTest.cpp since the last patch are correct?  should be pretty
trivial, it passes all cc_unittests.  Then I'll try the cq again.
