Get rid of one-off code in ScrollingCoordinator to handle graphics layer offsets.

This allows us to remove a redundant squashing-related property in RenderLayer,
and is also a step towards not having non-compositing code know about how the layers
are positioned & drawn.

Update GOM unittests to pass

Not sure why the tests changed from expecting '' to undefined,
but I doubt it matters.  Useful to be able to start from
all tests passing.

Floats following inlines break to next line unncessarily

Don't include trailing space in linewidth calculations when deciding
if a float can fit on a line.

Remove rebaseline logic from GOM

It's dead.  The auto rebaseline bot won.

Remove checkout functionality from GOM

Some folks still probably run GOM locally, but
it's not worth the burden on the code to keep this around.
If we want this we should re-build it to be web only.
