soc/intel/meteorlake: Conditionally update CSE sync UPDs in FSP-M

This patch updates FSP-M UPDs conditionally to ensure CSE firmware
updates and VGA initialization control only when
`SOC_INTEL_CSE_LITE_SKU` config is enabled.

This ensures eSOL rendering is tied to CSE sync performed in coreboot,
preventing unnecessary setup when sync is deferred to the payload.

Deferring CSE sync to the payload results in the depthcharge screen.

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
