qcacmn: Implement the commands that cover APF 3.0 requirements

Android Packet Filter 3.0 requires the framework to be able to
read and write into the APF work memory in the Firmware. It
also requires to be able to enable or disable the interpreter.
New WMI commands are defined for read/write/enable/disable
operations.

Complete the implementation of these new commands.
