Add support for multi game XCIs (#5638)

* Add default values to ApplicationData directly

* Refactor application loading

It should now be possible to load multi game XCIs.
Included updates won't be detected for now.
Opening a game from the command line currently only opens the first one.

* Only include program NCAs where at least one tuple item is not null

* Get application data by title id and add programIndex check back

* Refactor application loading again and remove duplicate code

* Actually use patch ncas for updates

* Fix number of applications found with multi game xcis

* Don't load bundled updates from multi game xcis

* Change ApplicationData.TitleId type to ulong & Add TitleIdString property

* Use cnmt files and ContentCollection to load programs

* Ava: Add updates and DLCs from gamecarts

* Get the cnmt file from its NCA

* Ava: Identify bundled updates in updater window

* Fix the (hopefully) last few bugs

* Add idOffset parameter to GetNcaByType

* Handle missing file for dlc.json

* Ava: Shorten error message for invalid files

* Gtk: Add additional string for bundled updates in TitleUpdateWindow

* Hopefully fix DLC issues

* Apply formatting

* Finally fix DLC issues

* Adjust property names and fileSize field

* Read the correct update file

* Fix wrong casing for application id strings

* Rename TitleId to ApplicationId

* Address review comments

* Fix formatting issues

* Apply suggestions from code review

* Gracefully fail when loading pfs for update and dlc window

* Fix applications with multiple programs

* Fix DLCWindow crash on GTK

* Fix some GUI issues

* Remove IsXci again
