[SPARK-35535][SQL][FOLLOWUP] Move LocalScan to Catalyst package

### What changes were proposed in this pull request?

This is a follow-up of #32678. It moves `LocalScan` from SQL core package to Catalyst package.

### Why are the changes needed?

There are two packages for `org.apache.spark.sql.connector`
SQL Core: https://github.com/apache/spark/tree/master/sql/core/src/main/java/org/apache/spark/sql/connector
Catalyst: https://github.com/apache/spark/tree/master/sql/catalyst/src/main/java/org/apache/spark/sql/connector

As `LocalScan` doesn't depend on the classes of SQL Core, we should move it to catalyst.
### Does this PR introduce _any_ user-facing change?

No, the trait is not released yet.

### How was this patch tested?

Existing UT.

Closes #33826 from gengliangwang/moveLocalScan.
