information_schema.columns table should have column info from views

[jennifersp]

the columns from mytable should be in information_schema.columns table but references to table_name = 'myview'

CREATE TABLE mytable (pk bigint, v1 bigint);
CREATE VIEW myview AS SELECT * from mytable;
SELECT ordinal_position as ordinal_position,column_name as column_name,data_type AS data_type,is_nullable as is_nullable,column_type as column_type FROM information_schema.columns WHERE table_schema='tempdb'AND table_name='myview';

+------------------+-------------+-----------+-------------+-------------+
| ordinal_position | column_name | data_type | is_nullable | column_type |
+------------------+-------------+-----------+-------------+-------------+
|                1 | pk          | bigint    | NO          | bigint      |
|                2 | v1          | bigint    | NO          | bigint      |
+------------------+-------------+-----------+-------------+-------------+

above is result from Mysql. Dolt returns empty result, so that the view structure is empty in TablePlus

VIEW structure is no longer empty, so they should show up. However, we are returning either NULL or empty string for many of the columns that are typically there for information_schema.columns. I think it would take a lot of changes to ViewDefinition in GMS to have this work correctly though.
