Restored some of the window awareness previously avail in raylib for the new sokol layer.

Switched frametime_delta32 to frametime_avg_ms.

I'll problably rename it and keept delta32 for actual delta. Reading over the sokol_app code I noticed it uses the avg frametime and definitely want to do that for spike alleviation...
