Bug 1068 - Allow GLContext creation and makeCurrent without default framebuffer (Part 2)

Implement surfaceless context on EGL and GLX/X11
utilizing *UpstreamSurfacelessHook as introduced in
commit 9ea218a5990b908e04235c407c0951c60df6ffba.

Surfaceless context is probed during GL profile probing by default.
If available, it will be used for offscreen FBO drawables.
If probing fails, or is disabled,
the new GLRendererQuirks.NoSurfacelessCtx is set.

- GLProfile.disableSurfacelessContext disables
  surfaceless context probing, set property 'jogl.disable.surfacelesscontext'

Tested:
  - Mesa/EGL works,
  - Mesa + NVidia w/ GLX fail on GNU/Linux): Fails NoSurfacelessCtx

- TODO: Windows impl. and more tests

+++

Bug 896: EGL_KHR_create_context (Part 1)

- Detect EGL_KHR_create_context capability and utilize if available.

- Implement EGLContext.createContextARBImpl(..),
  allowing native DEBUG context usage, where available.

- EGL implements SharedResourceRunner, i.e. probing profiles
  on dedicated thread using common interface.

- Probe desktop profile/context ability
  in EGLDrawableFactory SharedResourceRunner,
  Where EGLGLnDynamicLibraryBundleInfo covers EGL + desktop GL.

- TODO: Tests w/ capable implementation
