* 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)

`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
