soc/intel/cmn/cse: Refactor CBMEM ID handling for flexibility

This patch refactors the handling of CSE CBMEM IDs to enable platforms
to choose whether to perform CSE sync operations within coreboot or
defer it to the payload. This separation improves code organization,
ensuring `cse_lite.c` focuses on coreboot-specific CSE Lite tasks.

Now, platforms can select:
  * `SOC_INTEL_CSE_LITE_SKU` for CSE sync within coreboot
  * `SOC_INTEL_CSE_LITE_SYNC_BY_PAYLOAD` for deferred payload sync

This change ensures mutually exclusive options, avoiding unnecessary
SPI flash size increases.

BUG=b:305898363
TEST=Builds and boots successfully:
    * google/rex0 with SOC_INTEL_CSE_LITE_SKU
    * google/rex64 with SOC_INTEL_CSE_LITE_SYNC_BY_PAYLOAD
