Subject: [posix] expose `platformInfraIfIsRunning()` as
 `otSysInfraIfIsRunning()` (#9672)

When we are switching to another infra netif via
`otBorderRoutingInit()`, we may want to read the state of the new
infra netif via `otSysInfraIfIsRunning()`.

(cherry picked from commit 11622a1b4a9eccf03627e776c98c32dcac8748b7)
