wifi: rtw89: pre-handle RF calibration on link when needed

The Wi-Fi 7 RF calibration flow has a new design which mainly affect
MLO cases. Before, old RFK H2C command can just send the used channels
and MLO mode even if there are multiple active links. After, each RFK
H2C command should send one channel corresponding to one active link.

For example, connect MLD AP (channel X) and then activate second link
(channel X + channel Y)

Before:
	RFK#1: channel X (path A + path B)
	RFK#2: channel X (path A) + channel Y (path B)

After:
	RFK#1: channel X (path A + path B)
		[set MLO mode to focus on 2nd link/channel]
	RFK#2: channel Y (path A + path B)
		[set MLO mode back to target case]
