soc/intel/cmn/cse: Allow to perform essential CSE operations post EOP

This patch allows to send late EOP cmd to CSE (after CSE .final)
using boot state machine (either BS_PAYLOAD_BOOT or BS_PAYLOAD_LOAD)
if the SoC user selects SOC_INTEL_CSE_SEND_EOP_LATE config.

Rename `set_cse_end_of_post()` to `send_cse_eop_with_late_finalize()`
to make the function name more meaningful with its operation.

BUG=b:260041679
TEST=Able to boot Google/Rex after sending CSE EOP late.
