Message : Capture/Replay: Correct a few GLenum replay issues. This change refactors the GLenum utils into a non-autogenerated and an autogenerated portion. That makes it easier to modify the non-auto- generated bits to properly output GLenums even when the gl.xml data isn't totally correct. For instance, the "GetPName" group was missing a bunch of queries. Instead of trying to fix the GL we can simply fall back to querying the "Default" group when we return invalid enum. Also corrects a missing "0x" on hex output. Also allows the capture/replay sample to specify the correct binary data directory when testing a replay.
