soc/intel/common/cse: Skip CSE state setting with LITE_SYNC_BY_PAYLOAD

The CSE state setting logic in `cse_set_state` is not required when
the `SOC_INTEL_CSE_LITE_SYNC_BY_PAYLOAD` configuration option is
enabled.

This commit adds a conditional check to skip the state setting in such
cases, potentially optimizing the CBFS travering time to locate
`option/me_state` file.

TEST=Able to build and boot google/fatcat.
