wifi: ieee80211: add Radio Measurement action fields

Drivers that support Tx power insertion could examine the outgoing Radio
measurement packet and depending on the packet type, the driver can
insert specific data fields in it. These action field values will help
drivers classify the action code within the Radio Measurement action
packet.

These action fields are defined in IEEE 802.11-2024 - Table 9-470, Radio
Measurement Action field values.
