wifi: rtw89: ser: L1 add pre-M0 and post-M0 states

Newer FW re-design SER (syetem error recovery) L1 (level 1) flow.
New L1 flow will expect two extra states before original L1 flow.

* Before:
fw --- M1 --> driver
fw <-- M2 --- driver
fw --- M3 --> driver
fw <-- M4 --- driver
fw --- M5 --> driver

* After:
fw --- pre-M0  --> driver
fw <-- post-M0 --- driver
fw --- M1 --> driver
fw <-- M2 --- driver
fw --- M3 --> driver
fw <-- M4 --- driver
fw --- M5 --> driver

Then before M1, FW gets one more interval to deal with things that FW
should have handled well. To consider backward/forward compatibility,
FW and driver won't change flow from M1 to M5. (only except that halt
trigger control will change a little bit.) So, there will be two differnt
starting points of SER L1.
* old FW: SER L1 starts from M1
* new FW: SER L1 starts from pre-M0
Then, driver adds the new SER L1 entry and also keep the original one
instead of changing it.
