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().

  • Replace stubbed InitialProcessIdRange implementation with proper bounds (1-0x50)
  • Add handle and info_sub_id validation for InitialProcessIdRange
  • Replace process exit ASSERT with graceful error handling and logging
  • Add try-catch block around system.Exit() for safer shutdown
  • Add atomic header inclusion for binder.h

This improves system call reliability by properly implementing process ID
range checks and adding safer process exit handling with proper error logging.
