hle/ui: Basic multi programs support (#1560)
* hos/gui: Add a check of NCA program index in titleid

This add a check to `ApplicationLoader` for the last 2 digits of the game TitleId who seems to be the NCA program index.
We currently return the last index, instead of the lower one.
Same check is added to ApplicationLibrary in the UI.

I've cleaned up both file too.

* hle: implement partial relaunch logic

TODO: make the emulator auto relauch.

* Handle auto relaunch

* hle: Unify update usage system

* hle: Implement support of multi programs in update system

* Add some documentation

* Address rip's comment
