Camera: relay sync fence to vendor library

Currently, a sync fence from ParcelImage is not relayed to a vendor
library. However, a fence might be required to implement a service-based
vendor library.

This patch will make changes to dup/provide a fence to the vendor
library.

Bug: 363229739
Test: Manual test with service based vendor library
