Which issue does this PR close?

Closes #4347.

Rationale for this change

Currently CometLocalTableScanExec is disabled by default. A lot of Spark SQL tests (UDFs, expressions) don't write their input to sources that Comet reads natively (e.g., Parquet, Iceberg) so they are likely not being exercised through Comet.

What changes are included in this PR?

Enable localTableScan translation to Comet by default.

How are these changes tested?

Existing tests.
