Review Comment:
   Reasonable. The real bug is in schema change shadow-tablet materialization 
for non-base indexes.
   
   Changed:
   
   - Added Index.collectBloomFilterColumns(...) and 
Index.filterBloomFilterColumnsBySchema(...)
   - In SchemaChangeJobV2 and CloudSchemaChangeJobV2, materialize 
per-shadow-schema shadowBfColumns and pass them down instead of relying on 
tabletIndexes != null
   - Added FE UTs for local/cloud schema change rollup shadow replicas and a 
rollup regression case
