Add a shell command to force hi-perf mode

This commit adds the wifi shell command to force hi-perf mode.
This is equivelent to an app acquiring a WIFI_MODE_FULL_HIGH_PERF
wifiLock. Command syntax is:

$ adb shell cmd wifi force-hi-perf-mode (enabled/disabled)
where: enabled means hi-perf mode is forced no matter what apps require.
       disabled means mode is not forced, and left for apps.

Test: Manual testing of the command
Test: $ adb shell cmd wifi force-hi-perf-mode (enabled/disabled)
Test: Unit test
