soc/intel/common/block: Move cse common functions into block/cse

This patch cleans soc/intel/{cnl, icl, tgl} by moving common
soc code into common/block/cse.

Supported SoC can select existing HECI_DISABLE_USING_SMM option to
select common cse code block to make heci function disable using
sideband interface during SMM mode at preboot envionment.

BUG=b:78109109
TEST=Able to make HECI disable in SMM mode successfully without any hang
or errors in CNL, ICL and TGL platform.
