pillar/zedagent: Revert snapshot capability due to misleading support indication.

Rolling back the reported capability from CAPABILITY_VOLUME_SNAPSHOTS to
CAPABILITY_START_DELAY_IN_SECONDS in ReportDeviceInfo.

This change addresses the inconsistency where the UI indicated snapshot support
in versions prior to its actual implementation.

Noted that CAPABILITY_EDGEVIEW, which should technically precede, is commented
out in the API proto file.
