LibGL: Merge GLContext and SoftwareGLContext

This merges GLContext and SoftwareGLContext into a single GLContext
class. Since the hardware abstraction is handled via the GPU device
interface we do not need the virtual base of GLContext anymore. All
context handling functionality from the old GLContext has been moved
into the new version. All methods in GLContext are now non virtual and
the class is marked as final.
