Bug 1203: Optimize OpenGL Profile probing/mapping (Skip redundant queries)

Via GLDrawableFactory[Impl] the following details are considered
while GLContextImpl.mapGLVersions(..):
  - hasOpenGLDesktopSupport
    If false, skip OpenGL Desktop queries

  - hasOpenGLESSupport
    If false, skip OpenGL ES queries

  - hasMajorMinorCreateContextARB
    If false, reduce [maxMajor.maxMinor..minMajor.minMinor]
    iteration, reducing to [maxMajor..minMajor],
    usually only one query.
