Revert 96982 - Add gl.dll, compositor.dll, and surface.dll.

Revert 96982 - Add gl.dll, compositor.dll, and surface.dll.

I considered merging these into ui.dll, but the respective GYP files are pretty
customized, and merging all of the special casing into ui.gyp seemed like it
would just make things messy.  Plus, some components only need to link to
surface and not all of ui.

One thing that I'm not entirely sure about is the naming convention.  In this
case the modules are named gl, compositor and surface instead of ui_gfx_gl, and
so on.  I thought about declaring UI_GFX_GL_EXPORT, but I opted for the shorter
GL_EXPORT instead.  I think Ben has been thinking about moving these
directories out of ui/gfx/ anyways since it is a bit odd for them to live there.
