Add MGMT_RX_PROCESS test command for wpa_supplicant

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
wpa_supplicant to process a received a management frame, e.g., based on
information reported in the MGMT-RX events.
