Extend SHOW TABLES, DESCRIBE and SHOW COLUMNS to support table identifiers not just SQL LIKE pattern. This allows both Elasticsearch-style multi-index patterns and SQL LIKE. To disambiguate between the two (as the " vs ' can be easy to miss), the grammar now requires LIKE keyword as a prefix for all LIKE-like patterns. Also added some docs comparing the two types of patterns. Fix #33294
