Mingyu Chen 9634d21a28 [fix](info_db) avoid infodb query timeout when external catalog info is too large or is not reachable (#18662) ...

When query tables in information_schema databases, it may timeout due to:

There are external catalog with too many tables.
The external catalog is unreachable
So I add a new FE config infodb_support_ext_catalog.
The default is false, which means that when select from tables in information_schema database,
the result will not contain the information of the table in external catalog.

Describe your changes.
