Add MGMT_RX_PROCESS test command for hostapd

Browse source 
This makes it easier to write hwsim test cases to verify management
frame processing sequences with dropped or modified frames. When
ext_mgmt_frame_handling is used, this new command can be used to request
hostapd to process a received a management frame, e.g., based on
information reported in the MGMT-RX events.

This is more or less identical to the earlier wpa_supplicant commit
4de70e2330 ('Add MGMT_RX_PROCESS test
command for wpa_supplicant'), but for hostapd.
