wifi: rtw89: update D-MAC and C-MAC dump to diagnose SER

To detect TX or RX stuck, we implement SER (system error recovery) in
firmware to recover abnormal states of hardware, and report events to
driver. This kind of events could happen rarely per day.

SER might be true-positive or false-negative cases, and it could be failed
to recover true-positive case. We dump related registers to kernel message
at that moment and collect them from users, because they occur rarely,
randomly and hard to make sure we reproduce the same symptom. To address
problems accurately, add more registers by this patch.

It also might be false-positive cases that looks like TX or RX get stuck,
we need to dump registers from debugfs manually, so also add similar
things to debugfs as well.
