Rework tracing system and enum creators

- Rework tracing system, now using "{}" for formatting instead of the
  standard %s,%d,%f formatting that C++ uses.
- Rework enums creators to not take in namespace
- Fix single use CommandBuffers sometimes failing due to indexing them
  with the current frame in flight
- Add DropEvent to Window
