[routing-manager] add manual OMR prefix configuration on BR (#11365)
This commit introduces a new mechanism in `RoutingManager` to configure OMR prefix handling on a Border Router. This provides manual administration options to explicitly set a custom OMR prefix or disable it, in addition to the existing default behavior where the BR automatically selects and manages the OMR prefix. These new administrative configurations can also be used during testing, particularly for certification tests. This commit adds new public OpenThread APIs and a CLI command, `br omrconfig`, for this functionality. Notably, the new APIs allow updating the OMR configuration while the BR is enabled and running, and the implementation correctly adjusts to the new requested behavior. A new detailed test case is added to the `test_routing_manager` unit test, covering the new behavior.
