[SPARK-14410][SQL] Push functions existence check into catalog
## What changes were proposed in this pull request?
This is a followup to #12117 and addresses some of the TODOs introduced
there. In particular, the resolution of database is now pushed into session
catalog, which knows about the current database. Further, the logic for
checking whether a function exists is pushed into the external catalog.
No change in functionality is expected.
## How was this patch tested?
`SessionCatalogSuite`, `DDLSuite`
