vc/google/chromeos: Skip boot info logging if cse sync at payload

This patch skips event logging for current boot information at ramstage
if CSE sync is scheduled at payload. Given that CSE sync could initiate
a system reset, resulting in redundant boot information logs, the
payload should handle the logging of boot information following CSE
sync.

BUG=b:360082747
TEST=Verified elog boot info is not logged at ramstage
