[fix](cloud) Fixed uneven tablet performance during upgrades from old…
22365ad 
…er versions (#58135)

Prior to this #42986 PR, the
`getLastUpdateMs` field of the backend was not written to the fe image.
This caused the tablet mapping on the cloud to lose the PrimaryBackend
information after the upgrade, resulting in the regeneration of an
incorrect PrimaryBackend and uneven tablet distribution.
