Subject: HLE: Refactoring of ApplicationLoader (#4480)
* HLE: Refactoring of ApplicationLoader
* Fix SDL2 Headless
* Addresses gdkchan feedback
* Fixes LoadUnpackedNca RomFS loading
* remove useless casting
* Cleanup and fixe empty application name
* Remove ProcessInfo
* Fixes typo
* ActiveProcess to ActiveApplication
* Update check
* Clean using.
* Use the correct filepath when loading Homebrew.npdm
* Fix NRE in ProcessResult if MetaLoader is null
* Add more checks for valid processId & return success
* Add missing logging statement for npdm error
* Return result for LoadKip()
* Move error logging out of PFS load extension method
This avoids logging "Could not find Main NCA"
followed by "Loading main..." when trying to start hbl.
* Fix GUIs not checking load results
* Fix style and formatting issues
* Fix formatting and wording
* gtk: Refactor LoadApplication()
