MDEV-10000 Add EXPLAIN [FORMAT=JSON] FOR CONNECTION syntax support
EXPLAIN FOR CONNECTION is a MySQL-compatible syntax for SHOW EXPLAIN.
This commit also adds support for FORMAT=JSON to SHOW EXPLAIN,
so the possible options to get JSON-formatted output are:
- SHOW EXPLAIN FORMAT=JSON FOR $con
- EXPLAIN FORMAT=JSON FOR CONNECTION $con
