wifi: Remove usages of SystemProperites.set
a) Remove unused call to trigger bugreport from WifiConfigStorEncryptionUtil class.
b) Remove unnecessary call to increase HAL log level. This is now
directly handled inside the HAL in a linked CL.
c) Stop using ctl.start/ctl.stop to start/stop supplicant on older
HAL's. Use the new android.sysprop.InitProperties instead.
Bug: 144695435
Test: Manually verified that these @hide accesses no longer show up in
wifi-service dependency.
Test: Device boots up & connects to wifi networks.
