service/apt: Implement Deliver Args (#5611)

Browse Source 
* service/apt: Add GetModule and GetAppletManager

These will be used to retrieve and set deliver args across system resets (which are currently implemented as complete restarts)

* applet_manager: Implement DeliverArg

`flags` was added to `ApplicationJumpParameters` as flags 0x2 is handled differently from 0x0.

* service/apt: Add ReceiveDeliverArg, implement GetStartupArgument

Some based on guesses.

* Address review comments
