feat: Add Home Menu launch support and system improvements

This commit adds support for launching the system Home Menu and implements
several system-level improvements:

- Add Home Menu launch functionality through new UI action
- Implement shutdown/reboot sequence handlers in GlobalStateController
- Add support for reserved region extra size in page tables
- Enhance audio controller with output management
- Expand parental control service capabilities
- Add profile service improvements for user management

Technical changes:
- Add OnHomeMenu() handler to launch QLaunch system applet
- Implement m_alias_region_extra_size tracking in page tables
- Add new CreateProcessFlag for reserved region extra size
- Expand audio controller interface with output management
- Add self-controller methods to various services
- Implement play timer and profile service improvements

The changes primarily focus on system menu integration and core service
improvements to better support system functionality.
