Bug 1203: Implement regular EGL OpenGL Profile probing (ES* + GL*)

- GLProfile
  - Add 'hasGL234OnEGLImpl' handling, i.e. GL* profiles on EGL devices

  - Properly handle EGL's 'GLDynamicLookupHelper' queries for ES2, ES1 and GL* profiles,
    i.e. allow each one to fail seperately.

  - Merge computed EGL-Profile-Map (1) and Desktop-Profile-Map (2)
    per device, instead of just using the last computation,
    preserving and favoratizing the Desktop-Profile-Map.

- GLContextImpl.mapGLVersions(..): Map ES* profiles if having an EGLGraphicsDevice
  and not disabled via GLProfile.disableOpenGLES.

- EGLContext
  - createContextARBImpl(..): Use the EGL_CONTEXT_MINOR_VERSION_KHR if supported

  - GLContext* accessibility: Remove unused entries, add newly used ones

- EGLDrawableFactory
  - Fix a bug regarding detection of 'OpenGL' API for EGL

  - SharedResource: Use detailed knowledge of each profile

  - Only create one drawable and context for probing maximum,
    utilizing 'GLContextImpl.MappedGLVersionListener'
    to detect all mapped profiles for 'SharedResource' instance.

  - Detect whether the probed/mapped device
    can be mapped to the default-EGL-device, i.e.:
      - current device is not the default-EGL-device
      - default-EGL-device is valid and could be mapped (beforehand)
      - same connection
    In this case, no probing/mapping is performed
    and the default-EGL-device mapped data being reused and remapped
    to the requested device.

  - When mapping/probing, attempt to use a surfaceless context first,
    allowing same codepath for default-EGL-device and native-device (X11, ..).
    This avoids using pbuffer if using default-EGL-device
    and a dummy onscreen window if using a native-device (X11, ..).
    If this fails, continue as usual ..
      - default-EGL-device -> pbuffer
      - native-device (X11, ..) -> dummy onscreen window
