wifi: rtw89: debug: support SER L0/L1 simulation via halt H2C

Browse Source 
Original methods of SER (system error recovery) L0/L1 simulations need
to leave PS mode before working. Introduce new methods to simulate SER
L0/L1 and they can work under PS. Since new methods require FW support,
so add a FW feature flag and configure the supported chips.
