Reland "Move a good set of gfx unit tests into gfx_unittests target."

It was reverted in r270600 because it broke compilation:
lib/libgfx.so:error: undefined reference to 'XCreateRegion'
lib/libgfx.so:error: undefined reference to 'XUnionRectWithRegion'
lib/libgfx.so:error: undefined reference to 'XPolygonRegion'

Original description:
This requires to major changes:

1- It requires the introduction of GfxTestSuite to allow us to
initialize the ResourceBundle which is required for some of these tests
to pass.
2- It requires to split gfx_unittests target out of gfx.gyp, into
gfx_tests.gyp. This is necessary because otherwise a circular dependency
between ui_base.gyp and gfx.gyp would arise.

The circular dependency is the form of:
gfx.gyp -> ui_base.gyp -> gfx.gyp

And is created because gfx_unittests now requires ResourceBundle to link
which is in ui_base target.
