Filter pushdown performance for log table (FIP-10)

[xx789633]

Filter pushdown for log tables enables early filtering at the storage layer before decompression and deserialization, thereby dramatically improving query performance for non-primary key and non-partition key filters. See FIP: https://cwiki.apache.org/confluence/display/FLUSS/%5BWIP%5DFIP-10%3A+Support+Log+RecordBatch+Filter+Pushdown

In this issue, we evaluate the performance improvement achieved by this FILTER pushdown optimization.
