Thibault Saunier e835042f04 ges: Add APIs to have a sens of frame numbers
APIs:
   - ges_timeline_get_frame_time
   - ges_timeline_get_frame_at
   - ges_clip_asset_get_frame_time
   - ges_clip_get_timeline_time_from_source_frame

Extracting ges_util_structure_get_clocktime to internal utilities adding
support for specifying timing values in frames with the special
f<frame-number> synthax.
