[MINOR][SQL] Put the grammar of database together, because this is good for maintenance and readability.
## What changes were proposed in this pull request?
The SQL grammar `SHOW DATABASES` is mixed in some grammar of table. I think should arrange the grammar of database together.
This is good for maintenance and readability.
## How was this patch tested?
No UT
Closes #24138 from beliefer/arrange-sql-grammar.
