applets: Implement backend and default frontend for Parental Controls and EShop (ShopN) applets

glue: Implement arp:w and arp:r services

Avoids using system accessor to get current process in applet code.

Prevents crashes with ShopN applet occasionally.

If it is needed but wasn't passed (or passed nullptr), the Shop handling code will alert and throw an error.

Allows easy handling of multiple shim types, as they have enough in common to be the same backend but not enough to share init/exec.

Much, much more HW-accurate and allows us to easily support all of the different web 'shim' types.

This is more representative of what actually occurs, as web does support remote URLs which wouldn't need a romfs callback. This paves for easy future support of this with a call like 'OpenPageRemote' or similar.

This is responsible for parental controls and supports verifying, changing, and registering PIN codes.

These keep track of running process' launch properties and control properties and allows for issuing and reading them by process and title ID.

Glue is the name of the sysmodule that contains both arp and bgtc.

Manages mapping between title IDs and application launch and control properties.

Used to determine StorageId source for application data.

The sanitizing function ensures that the returned type is always the
correct type. This eliminates warnings without extra casts.

Update content_archive.cpp

Even though it has been proven that IAudioRenderer:SystemEvent is 
actually an automatic event. The current implementation of such event is 
all thought to be manual. Thus it's implementation needs to be corrected 
when doing such change. As it is right now this PR introduced a series 
of regressions on softlocks on multiple games. Therefore, this pr 
reverts such change until a correct implementation is made.
