Test updating underlying network of IpSecTunnelInterface

This CL adds tests to verify that after setting
IpSecTunnelInterface to use a different undelying network and
re-applying IpSecTransforms with matching addresses, traffic
can be routed to/from the new underlying network.

All these new tests will be skipped if SDK < S

Bug: 169855650
Test: atest IpSecManagerTunnelTest (new tests added)
