[test] add testResetInstance() to simulate device reset (#12878)

Browse Source 
This commit introduces `testResetInstance()` in the unit test platform
layer to finalize an existing `ot::Instance` and re-initialize it
using the same underlying memory buffer, simulating a device reset.

This commit also updates `test_routing_manager.cpp` to use this new
function to streamline the test implementation.
