Polish developer option enable verbose vendor logging 

Robotests cases in EnableVerboseVendorLoggingPreferenceControllerTest
show all pass but actually they are all bypassed due to the fact that
the test class can not grant sepolicy permission as what Settings
app does.

This version introduces mock DumpstateDevice HAL to really
perform the Robotests cases.

This CL also clear up code format issues.
