cnss2: Add support for handling AFC memory request from FW

Add APIs for handling AFC memory request from FW:
cnss_send_buffer_to_afcmem() and cnss_reset_afcmem().

cnss_send_buffer_to_afcmem() will be called if receive valid AFC
response data, cnss_reset_afcmem() will be called if receive
invalid AFC response data. After memory copy done, another WMI
command will indicate FW ready to read.

Add FW memory type QMI_WLFW_AFC_MEM_V01.
