wifi: rtw89: debug: add diagnosis for RF

Browse source 
Add debugfs diag_rf and show RFK (RF calibration) diagnosis things for
now. Record channel related info before triggering RFK, and then record
state of each kind of RFK from C2H event report. Besides, in track work,
monitor TSSI status too. Both support history up to 10, and show records
via debugfs.

The following is an example of output.

Debugfs diag_rf can also be used to manually trigger RFK when written by 1.
