SenseApiDesc,xcbWindow: port to sscl coro framework

SenseApiDesc's exported API now uses coro pointers instead of
CPS fn pointers.
* Do not build this version of SMO with the Livox drivers enabled,
  because SMO has been changed at the smocore level to use coros
  when calling into stimbuffAPI libs. But the Livox drivers
  haven't yet been ported from CPS to coros.

xcbWindow has been ported to expose coros to SMO in its
senseApiDesc exported iface.
