Expose Get/Set BootSourceOverrideTarget via SystemRegistry

Expose BootSourceOverrideTarget getter and setter in tlbmc SystemRegistry HAL to support Redfish out-of-band boot configuration.

Similar to BootNext, BootSourceOverrideTarget maps to gbmc-settings backed storage for out-of-band boot configuration.

- Add GetBootSourceOverrideTarget and SetBootSourceOverrideTarget to SystemRegistry interface.
- Implement methods in SystemRegistryImpl delegating to SettingsManager.
- Add mock methods in MockSystemRegistry.
- Add unit tests in system_registry_impl_test covering default, update, and invalid ID handling.
