Bug fix channel utilization during high traffic

In some wifi hal implmentation, ccaBusyTime includes the device's own packet Rx time which results in high channel utilization during full-buffer downlink throughput test. The fix is to add config_wifiChannelUtilizationOverridingEnabled to allow OEM to use fixed band-dependent values. These band-dependent values are programmable through overlay.

Test: atest com.android.server.wifi
Test: manually check reported cca level during iperf downlink and uplink test
