fix(go/adbc/driver/snowflake): workaround snowflake metadata-only limitations

[zeroshade]

Workaround to fix #1454 until snowflake addresses snowflakedb/gosnowflake#1110 with a better solution (hopefully by having the server actually return Arrow...)

@davidhcoe I've added a test that simulates the case where you running into an issue in order to confirm that it fixes the problem. But it would still be great to get you to test this with your SHOW TABLES example to confirm that this fixes that scenario too

I will try it either later tonight or early tomorrow at the latest.

oh joy

Ok, we can wait for @davidhcoe to give this a spin and then merge

@lidavidm I emphasized on the linked snowflake issue that this is a workaround and short-term solution. If snowflake ever decides to change their JSON format (since they aren't using valid JSON) or something, they'll break us. but I can't find a better workaround / solution to this unless snowflake fixes it on their server side.

Works great. Two thumbs up. Thank you @zeroshade.

Yup. If it breaks, we can redirect people to Snowflake as there's only so much we can do here.
