kernel: panic: Option ASSERT_NO_FILE_INFO controls panic or oops print

Browse source 
Use option ASSERT_NO_FILE_INFO to control panic or oops location print.
The cause of the exception can be backtraced using the stackframe
instead, which would give the user a way to reduce the footprint of the
panic implementation.
