cogl/frame-info: Add HW_CLOCK flag

Browse Source 
A flag indicating whether the presentation timestamp was provided by the
display hardware (rather than sampled in user space).

It will be used for the presentation-time Wayland protocol.

This is definitely the case for page_flip_handler(), and I'm assuming
this is also the case for the two instances in the GLX code.
