[SPARK-17257][SQL] the physical plan of CREATE TABLE or CTAS should take CatalogTable

## What changes were proposed in this pull request?

This is kind of a follow-up of https://github.com/apache/spark/pull/14482 . As we put `CatalogTable` in the logical plan directly, it makes sense to let physical plans take `CatalogTable` directly, instead of extracting some fields of `CatalogTable` in planner and then construct a new `CatalogTable` in physical plan.

## How was this patch tested?

existing tests.
