wifi: rtw89: mlo: handle needed H2C when link switching is requested by stack

To switch link, FW needs H2C commands to indicate which link is on or off.
Originally, these H2C commands are considered only when the link switching
is initiated by driver. But, in some cases, e.g. ml_reconf or TTLM, link
switching would be initiated by stack. Hence, plan these H2C commands into
ieee80211_ops.
