rtw89: ser: dump memory for fw payload engine while L2 reset
When FW encounters exception or assertion, SER L2 reset process will start.
It will dump some error information and re-download FW eventually. Since
such errors are usually critical, we would like to keep more information
about error to increase possibility of analysis and debugging FW. We first
add FW payload engine (fw reserved playoad engine, fw_rsvd_ple) memory
dump. FW will record things like CPU registers, backtrace entry, etc. in it
for debugging.
Moreover, device core dump framework is used and wrapped to collect kinds
of dumps during SER L2 reset process.
