Huaxin Gao 492d5d174a [SPARK-32171][SQL][DOCS] Change file locations for use db and refresh table
### What changes were proposed in this pull request?

docs/sql-ref-syntax-qry-select-usedb.md -> docs/sql-ref-syntax-ddl-usedb.md
docs/sql-ref-syntax-aux-refresh-table.md -> docs/sql-ref-syntax-aux-cache-refresh-table.md

### Why are the changes needed?
usedb belongs to DDL. Its location should be consistent with other DDL commands file locations
similar reason for refresh table

### Does this PR introduce _any_ user-facing change?
