Summary:
This patch implements using EGL_IMG_context_priority to request
high-priority rendering contexts if the extension is available.
EGL_IMG_context_priority is currently used in this fashion by
e.g. Android's SurfaceFlinger (RenderEngine.cpp) and libweston
(gl-renderer.c) and seems promising given this widespread
acceptance.

Summary: `abstract_egl_backend.cpp` includes several kwayland headers, but the include paths aren't added for kwayland. This patch solves the problem, by adding kwayland as requirement for the opengl scene plugin.

Summary:
Unfortunately a rather large change which required more refactoring than
initially expected. The main problem was that some parts needed to go
into platformsupport so that the platform plugins can link them. Due to
the rather monolithic nature of scene_opengl.h a few changes were
required:
* SceneOpenGL::Texture -> SceneOpenGLTexture
* SceneOpenGL::TexturePrivate -> SceneOpenGLTexturePrivate
* texture based code into dedicated files
* SwapProfiler code into dedicated files
* SwapProfiler only used in x11 variants
* Safety checks for OpenGL scene moved into the new plugin
* signal declared in SceneOpenGL moved to Scene, so that we don't need
to include SceneOpenGL in composite
Test Plan: Nested OpenGL compositor works
