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.

- Remove Unknown5000 function and related debug commands
- Fix incorrect service name in log message

- Add Unknown5000 implementation to create duplicate controller interface
- Add new debug-related command handlers:
  * OverrideDefaultTargetForDebug (50001)
  * SetForceOverrideExternalDeviceNameForDebug (50003)
  * ClearForceOverrideExternalDeviceNameForDebug (50004)
- Add proper debug logging for interface creation
- Update header with new function declaration
- Fix missing commas in function registration array

These changes improve the audio controller implementation by
adding support for interface duplication and debug override
functionality. The implementation maintains proper interface
lifetime management using SharedFrom.
