Make main app fully independent from the stub

- Skip 0x7f01XXXX - 0x7f05XXXX resource IDs in the main app; they are
reserved for stub resources
- Support sending additional data from host to guest
- Use resource mapping passed from host when they are being sent
to the system framework (notifications and shortcuts)
