CFSQL-1261: remove the need for d1 to patch wrangler for testing

[alsuren]

relates to CFSQL-1261

Describe your change...

On the D1 team, we are internally carrying a patch to add some fake location hints to create d1 databases in our internal staging environments.

When pairing with @penalosa , he thought that it would be better to make this into an environment variable so we don't have to carry a patch. This will make it easier to keep up with wrangler releases automatically in future.
