WifiManagerTest: Check if scan is currently available

Browse Source 
Changes in the CL:
a) Separate the scan part of testWifiManagerActions test into a
separate test.
b) The new scan test should check the |WIFI_SCAN_AVAILABLE| broadcast to
determine if the scan is expected to pass or not.

Bug: 72863107
Test: `atest
android.net.wifi.cts.WifiManagerTest#testWifiManagerActions`
Test: `atest
android.net.wifi.cts.WifiManagerTest#
