Bug fix for generated columns when creating a primary key

[zachmu]

This PR implements the parser changes in dolthub/go-mysql-server#2861 and adds tests.

There are still bugs around quoting in generated columns that need to be fixed in GMS, which will come in a follow-up PR.

1. These are tests that we're marking as Successful, however they do not match the expected output in some way. This is due to small differences, such as different wording on the error messages, or the column names being incorrect while the data itself is correct. ↩
