wifi: rtw89: phy: add H2C command to send detail RX gain and link parameters for PS mode

Introduce support for a new PS multi-link common info version (v1)
for RTL8922D, enabling the driver to send detailed RX gain and link
parameters to firmware via a new H2C command.

A dedicated 20 MHz beacon channel (chan_bcn) that replicates the primary
channel and band type of the original channel but forces a 20 MHz width.
This ensures that beacon mode always reference the 20 MHz gain table,
fixing the mis-assignment that could degrade signal strength or cause
incorrect RSSI calibration.
