opengl: add debug:gl_debugging (#13183)

Browse source 
add debug:gl_debugging so we can disable gl debugging entirerly,
both glGetError and enabling EGL_KHR_debug has its cost, we still have
EXT_create_context_robustness and glGetGraphicsResetStatus that should
catch context loss, and is generally cheap to call it only checks a flag
set.

glGetError might cause a implicit flush to get any pending calls sent to
the gpu.

however to get EGL_KHR_debug back enabled we now require a restart of
the compositor after changing debug:gl_debugging
