More getters for GlPlatform

A few more getters for parsed information are added to GlPlatform.
This includes the driver information retrieved through glGetString
and information like direct rendering and loose binding.

Additionally the methods to convert version, driver and chipClass
to string are added to the public interface.

These changes allow parts outside GlPlatform to get the same debug
information about the GL system.
