wifi: rtw89: fw: use generic flow to set/check features

Browse Source 
In early feature bitmap obtained from rtw89_early_fw_feature_recognize(),
the bits needed to check get increased. It's more friendly to work with
RTW89_CHK_FW_FEATURE(). So, we concentrate the flow of iterating FW feature
configures and calling RTW89_SET_FW_FEATURE() for various uses. And then,
we adjust rtw89_early_fw_feature_recognize() for RTW89_CHK_FW_FEATURE().
