add render timer API

Browse source 
Based on five calls:
wlr_render_timer_create - creates a timer which can be reused across
  frames on the same renderer
wlr_renderer_begin_buffer_pass - now takes a timer so that backends can
  record when the rendering starts and finishes
wlr_render_timer_get_time - should be called as late as possible so that
  queries can make their way back from the GPU
wlr_render_timer_destroy - self-explanatory

The timer is exposed as an opaque `struct wlr_render_timer` so that
backends can store whatever they want in there.
