wifi: Add AP bridge operations support (AP+AP Part 2)

The bridge interface name will take "ap_br_" + ap interface name.
ex: The ap interface name is "wlan1".
The bridge interface name will be "ap_br_wlan1"
When OEM customize the ap interface name via property
"ro.vendor.wifi.sap.interface".

It will only apply on single AP mode.
i.e.
"ro.vendor.wifi.sap.interface" = "sap0"
Single AP mode: ap interface name = "sap0"
Dual AP mode:
bridge interface name = "ap_br_sap0"
first ap instance name:  get from "getSupportedIfaceName" + idx
ex: sap0
second ap instance name: get from "getSupportedIfaceName" + idx + 1
ex: sap1

PS: The VtsHalWifiApV1_5TargetTest will be added in another CL which
will update another SAP related HAL:IWifiApIface.hal.

AP+AP Part 2 includes:
1. Support bridge in libwifi_system_iface
2. WifiHal API
a. createBridgedApIface (Support create bridge mode AP)
b. removeIfaceInstanceFromBridgedApIface (Support remove one of the instance in bridge)
3. Framework:
Create bridge AP when multi-bands configured.
