This commit introduces multiple improvements to IPC handling and system management services, enhancing game compatibility and emulator stability.
--- 1. Fully Implemented QueryPointerBufferSize Service:
- Exposes the per-process IPC pointer buffer size through `QueryPointerBufferSize` instead of returning stubbed values.
- Added `m_pointer_buffer_size` field to `KProcess`, initialized with a safe default (0x8000).
- Introduced getter and setter methods (`GetPointerBufferSize()` / `SetPointerBufferSize()`).
- Registered new handler in `sm_controller` for handling QueryPointerBufferSize requests.
- Ensures accurate buffer size reporting for games relying on this service.
--- 2. Automatic Pointer Buffer Sizing Per-Game:
- Automatically determines heap size by parsing `main.npdm` from the game’s ExeFS:
- Heap size > 1 GiB → pointer buffer size set to `0x10000`.
- Heap size > 512 MiB → pointer buffer size set to `0xC000`.
- Otherwise, defaults to `0x8000`.
- Gracefully handles missing or malformed `main.npdm` by falling back to default settings.
- Automatically configures pointer buffer size during `AppLoader_NCA::Load`.
- Added logging for heap size detection and buffer size configuration for easier debugging.
--- 3. SM Service Improvements:
- Added full implementation of `QueryPointerBufferSize` within the SM service framework.
- Cleaned up stubbed methods and ensured correct domain handling.
- Registered new service commands (e.g., `SetPointerBufferSize` and `QueryPointerBufferSize`) in `sm_controller`.
- Improved session handling with proper conversion to domain objects where necessary.
--- Benefits:
- Greatly improves compatibility with games that require larger IPC pointer buffers
- Eliminates the need for manual per-game pointer buffer overrides.
- More accurate emulation of Switch system services, improving stability for both commercial titles and homebrew.
- Provides cleaner logging for easier debugging and maintenance.
- Future-proofs IPC handling for upcoming titles with higher memory demands.
--- Additional Notes:
- Default pointer buffer size remains 0x8000 for smaller titles or if heap size cannot be determined.
- Falls back to safe defaults without affecting overall emulator performance.
- All new service calls properly registered and integrated without breaking existing functionality.
- Updated Horizon OS version to 19.0.1 and NintendoSDK version to 1.0. Adjusted `VERSION_HASH`, `DISPLAY_VERSION`, and `DISPLAY_TITLE` to match the new firmware versions.

Updates the OpenDisplay function in IApplicationDisplayService to properly
validate display names. Instead of only accepting "Default", now validates
against all known valid display names: "Default", "External", "Edid",
"Internal", and "Null".
- Changes log level from WARNING to DEBUG since this is no longer stubbed
- Adds proper validation for all valid display names
- Returns ResultOperationFailed for invalid display names
- Improves logging by including the requested display name
- 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.
Commit from Suyu, looks like Yuzu devs forgot to initialize memory here.
Comment from darktux: I've changed the use of memset to std::fill.

Adds support for InfoType::SystemResourceSize (0x1C) which is required for
proper initialization of the Virtual Address Memory Manager (VAMM). This
implementation:
1. Adds SystemResourceSize to the InfoType enum in svc_types.h
2. Implements the GetInfo handler for SystemResourceSize in svc_info.cpp
3. Returns 512MB (0x20000000 bytes) as the system resource size
4. Adds debug logging for the SVC call
The 512MB value is chosen based on typical system resource allocations
needed for VAMM initialization on the Nintendo Switch.
This fixes crashes in games that rely on VAMM functionality, particularly
during nn::os::detail::VammManager::InitializeIfEnabled().
Updated the ssl stubs to implement ssl:s for Firmware 19
This should make Xenoblade X: Definitive Edition bootable
