OpenGL ES/EGL Overhaul

- GLProfile properly detects native EGL/ES1/ES2 on the 'desktop' device factory.
  This allows usage of Mesa's EGL/ES or Imageon's PVR emulation, etc.

- GLProfile drops getDefaultDesktopDevice() and getDefaultEGLDevice()
  since both are aligned by getDefaultDevice().

- Fix GL_ARB_ES2_compatibility detection and utilize
  resulting isGLES2Compatible() where possible.
  This allows ES2 compatible desktop profiles to use core ES2 functionality
  (glShaderBinary() .. etc) even with a GL2ES2 desktop implementation.

- EGLDrawable: If createSurface(..) fails (BAD_NATIVE_WINDOW) w/ surfaceHandle
  it uses windowHandle if available and differs.
  This allows the ANGLE impl. to work.

- Properly order of EGL/ES library lookup:
  ES2: libGLESv2.so.2, libGLESv2.so, GLES20, GLESv2_CM
  EGL: libEGL.so.1, libEGL.so, EGL

- *DynamicLookupHelper reference will be null if it's library is not complete
   (all tool libs, all glue libs and a ProcAddressFunc lookup function - if named).

- Enhance GL version string (incl. ES2 compatible, hw/sw, ..)

- GLBase: Fix docs and remove redundancies

- Prepared (disabled) DesktopES2DynamicLibraryBundleInfo
  to be used for a real EGL/ES2 implementation within the desktop GL lib (AMD).
  Sadly it currenly crashed within eglGetDisplay(EGL_DEFAULT_DISPLAY),
  hence it's disabled.
