Subject: [PATCH] Core: Add libSceRtc, libSceJpegDec, libSceJpegEnc, and
 libScePngEnc LLEs (#3918)

* Run libSceRtc LLE

The more we've used our HLE, the more issues we've had with it.
While we debug these bugs, re-enabling LLE will address any regressions the swap caused.

* libSceJpegDec LLE

Needed for Trackmania until we implement HLE for this library

* libScePngEnc LLE

Needed for Minecraft until we implement HLE for this library

* Update documentation appropriately

* libSceJpegEnc LLE
