### What problem does this PR solve?
Issue Number: None
Related PR: #62867
Problem Summary: Delete rowsets can carry only the columns needed by their
predicates and omit indexes after a light schema change. MetaService treated
those inline schemas as authoritative: commit and restore paths could write
them to shared schema KV, while get-rowset and retry collision paths could
reuse them for normal rowsets with the same schema version. This could produce
schema mismatches and fail later normal rowset commits. Keep delete rowset
schemas inline and rowset-local, and exclude them from shared schema writes and
reuse in both legacy and versioned metadata modes.
### Release note
Prevent Cloud MetaService delete rowsets from corrupting or being reused as
shared tablet schemas.
