Purpose
Spark 4 changed ReplaceTableAsSelect to use OverwriteByExpression instead of AppendData,
which requires TRUNCATE or OVERWRITE_BY_FILTER capability.
External format tables (with location) go through PartitionedCSVTable (Spark FileTable),
whose default capabilities {BATCH_READ, BATCH_WRITE} don't include OVERWRITE_BY_FILTER.
The fix adds OVERWRITE_BY_FILTER to PartitionedFormatTable trait.
