Handle bool type conversion for "unknown" types

[jycor]

It is possible for a bool (and probably other types) to be an "unknown" type. We blindly assumed they would all be strings, leading to panics.
For fear of breaking other stuff, I didn't implement any other types.

Depends on:

• [no-release-notes] fix tests related to coster changes dolt#11208
• Add right side lookup overhead for LookupJoins go-mysql-server#3585

Footnotes

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. ↩
