[roll] Roll fuchsia [wlansoftmac] Merge WlanSoftmacBridge server dispatcher into main device dispatcher

The `WlanSoftmacBridge` server (served by `SoftmacBridge`) can run on
the main device dispatcher without causing deadlock because
`SoftmacBridge` never makes a blocking call.

Test: Successful iface creation, scan, connect, disconnect with iwlwifi on NUC
