Eventually we might want to have an XCB-based EGL winsys. We already have xlib-specific API in CoglRenderer (eg, to set a foreign display) so the application needs to be able to specifically select between XCB and XLIB. This also removes the POWERVR part while renaming COGL_HAS_EGL_PLATFORM_POWERVR_X11_SUPPORT to COGL_HAS_EGL_PLATFORM_XLIB_SUPPORT because the winsys is equally applicable to Mesa.
