Implement SwiftShader GL for Ozone.

Add working SwiftShader GL implementation for Ozone. There is no
platform specific FBO implementation for Ozone. However, SwiftShader can
still render into a pbuffer object.

Add a GLSurface implementation that is backed by a pbuffer and then use
glReadPixels() to copy pixels into memory. Add an X11 implementation
which copies the pixels into the XWindow. This provides a SwiftShader GL
implementation that works with Ozone X11 for the CrOS CQ trybots.
