Subject: [PATCH] [simulation] add empty `otPlatInfraIf` platform APIs in
 simul/test (#6852)

This commit adds empty implementations of `otPlatInfraIf` platform
APIs under simulation. It also adds `otPlatInfraIfHasAddress()` in
`test_platform`. This allows the unit tests and simulation platform
builds to succeed when `OPENTHREAD_CONFIG_BORDER_ROUTING_ENABLE` is
enabled.
