ozone: Create a separate small gfx_ozone target.

Instead of bundling up the ozone stuff into the larger gfx.gyp:gfx target,
split up the ozone-related code into a smaller gfx_ozone target with a
small dependency (base, skia). This allows ozone-platforms to implement
the ozone interface without bringing along the rest of gfx.
