feat(database): add set data type

[MrYamous]

Part of #547 to add the set data type to the table statements

To be honest I have a doubt about this implementation.
I think it can be confusing for end users to silently ignore this data type if not supported by the database. I did so inspired by BelongsTo or DropConstraint statements but I prefer the way it's done in ShowTables which throw an UnsupportedDialect exception.
But this broke tests (or at least, I don't know how to handle multiples cases from a Dialect to an other)

Btw I think it can be a good point to try to be consistent in how handle this situation

I agree.

I want to help figure this out with you, because indeed it's important to get this right. Could you maybe push the version with the exception, that way I can play around with it some more and see what happens in the tests

@brendt I've come up with an idea to deal with this situation, so I'm back with a new version that tests all the cases, including UnsupportedDialect Exception, and green CI :) but that I find very verbose

[brendt]

This looks good, what did you find too verbose about it?

Nevermind, if it's good for you it's good for me

I'll send another PR a bit later to use this Exception in other statements for consistency as suggested in my first message

Perfect, thanks!
