qcacld-3.0: Provide SME API to send unit test command to FW

Current driver forming a unit test command within HDD layer and uses
message passing method to deliver it to WMA layer which
requires HDD layer to have a knowledge of how to form a unit test command.

User SME API to send params to WMA layer and let WMA form a unit test
command and send it directly to FW through WMI layer instead of HDD
forming and passing it down.
