{commonlib, soc/intel/cmn/cse}: Store CSE firmware version into CBMEM

The patch implements an API that stores the CSE firmware version in the
CBMEM table. The API will be called from RAMSTAGE based on boot state
machine depending upon CSE sync config options
(`SOC_INTEL_CSE_LITE_SYNC_IN_ROMSTAGE` or
`SOC_INTEL_CSE_LITE_SYNC_IN_RAMSTAGE`).

Additionally, this patch adds a configuration option,
'SOC_INTEL_STORE_CSE_FPT_PARTITION_VERSION', which enables the storage
of firmware version information in CBMEM memory. This information can be
used to identify the firmware version that is currently installed on the
system. The option depends on the `DRIVERS_INTEL_ISH` config and
platform should be flexible enough to opt out from enabling this
feature.

The cost of sending HECI command to read the CSE FPT is significant
(~200ms) hence, the idea is to read the CSE RW version on every cold
reset (to cover the CSE update scenarios) and store into CBMEM to
avoid the cost of resending the HECI command in all consecutive warm
boots.

Later boot stages can just read the CBMEM ID to retrieve the ISH
version if required.

Finally, ensure this feature is platform specific hence, getting
enabled for the platform that would like to store the ISH version into
the CBMEM and parse to perform some additional work.
