cnss2: Add code to update feature list if WLAN_EN gpio supported

Add code to update feature list with CNSS_WLAN_EN_FEATURE flag
if WLAN_EN gpio is supported, the host indicates to firmware
about the WLAN_EN support via the feature list which is sent as
part of host capability qmi message. This would help firmware
to decouple the PERST in RDDM for MSM targets.
