qcacmn: Add support to print candidate rssi in kmsg 

First Requirement:
In case of WTC_BTM roam trigger reason, if FW reports rssi
threshold for 5G and 6G AP via wmi_roam_trigger_reason,
Host should print it in kmsg.

If wtc_candi_rssi_ext_present is set (1), It means fw
reports 5g and 6g candidate rssi (new firmware case).
If wtc_candi_rssi_ext_present is clear (0), It means fw
doesn’t report 5g and 6g candidate rssi (old firmware case).

Host use flag "wtc_candi_rssi_ext_present" to keep backward
compatibility.

Second requirement:
As per user space, value for scan mode in WTC command, is
like below:
0: no Scan, 1: partial scan and 2: full scan.

For NO scan case, FW sends value
ROAM_TRIGGER_SCAN_MODE_NO_SCAN_DISCONNECTION (3)
in wmi_roam_trigger_reason-> wtc_scan_mode. When driver receives
WTC scan mode as ROAM_TRIGGER_SCAN_MODE_NO_SCAN_DISCONNECTION,
it should print value as 0 instead of 3.

Convert WTC scan mode comes from FW to
wmi_configure_roam_trigger_parameters->scan_mode to make it
compatible to WTC command.
