Activate phcsync_warm_reboot_gate.py when syncd starts instead of invoking phcsync.sh directly.

This PR is related to:
zili11720/sonic-buildimage#11
zili11720/sonic-swss-common#2

Together, these PRs introduce an event-driven mechanism that starts and stops phcsync.sh during a warm reboot.

Order of merge:

  1. [Mellanox] Add waitWarmBootStarted to restartWaiter sonic-swss-common#2
  2. [Mellanox] Add phcsync warm reboot gate to avoid sync during warm reboot sonic-buildimage#11
  3. [Mellanox] Activate phcsync gate to prevent clock sync during warm reboot #2
