Add per-frame time and latency measurements

Timing is measured with a glQueryCounter(GL_TIMESTAMP) on every frame.

Latency is measured by comparing glGetIntger(GL_TIMESTAMP) which gets
the timestamp synchronously to a glQueryCounter(GL_TIMESTAMP) which
gets the timestamp asynchronously by inserting a command into the
OpenGL queue.
