[SPARK-18594] [SQL] Name Validation of Databases/Tables
### What changes were proposed in this pull request?
Currently, the name validation checks are limited to table creation. It is
enfored by Analyzer rule: `PreWriteCheck`.
However, table renaming and database creation have the same issues. It
makes more sense to do the checks in `SessionCatalog`. This PR is to add it
into `SessionCatalog`.
### How was this patch tested?
