qcacmn: Add WMI changes for Dynamic HW mode configuration

This feature enables user to change HW mode dynamically
from DBS to DBS_SBS mode and vice-versa. Currently, HW
mode configuration is only possible through INI setting
requiring a subsequent reboot.

Relevant WMI changes are:

1. Relocate API wmi_unified_soc_set_hw_mode_cmd from
wmi_unified_sta_api.c to wmi_unified_api.c
2. Define API wmi_unified_extract_hw_mode_resp to extract
FW response
3. Parse and store new dev-cap fields wireless_modes,
low_2ghz_chan_freq, high_2ghz_chan_freq, low_5ghz_chan_freq,
and high_5ghz_chan_freq.

CRs-fixed: 2490212
