Daniel Black 5bd91f6c0e MDEV-27898 CREATE VIEW AS SELECT FROM JSON_TABLE column requires global privileges ...

JSON_TABLE is marked as a special "*any_db*" table. Because this special
marking is processed all the way though to get_column_grant where
its processed like its in database called "*any_db*". As this
doesn't exist, only those users with global privileges can create
views on a JSON_TABLE.

Under a Prepared Statement protocol a Create_tmp_table is
used for the JSON_TABLE, but it gets assigned an "" database
name.

We correct this to give it "*any_db*" like the SQL parser
indicating that no database is needed.

To commonly correct the fill_effective_table_privileges
by looking explictly for the "*any_db*", those tables that
have this as the database name get SELECT privileges.

While correcting the database for the JSON_TABLE, lets give
it a "json_table" name rather than "(temporary)" for
greater clarity in warning messages.
