[neil-ptr]

Description

This pr implements recursive queries through the use of the new $withRecursive method to be used as such

const employeeHierarchy = db.$withRecursive('employeeHierarchy').as('recursive query here...');
 
const result = await db.with(employeeHierarchy).select().from(employeeHierarchy);

Comments and suggestions are welcome.

closes #209
depends on PR #1218

@neilZon I see that you started this PR. I have a couple initial commits in my fork as well. I didn't want to create a PR because it depends on #1218 and it will also close #372
Please take a look at how I have working right now: https://x.com/Angelelz/status/1708368486634819916?s=20
You can also check the branch with my commits, currently only working for Mysql. The problem is that the union PR will have substantial changes as there was a lot of changes to the beta branch of drizzle.

@neilZon thanks for your work!
@Angelelz was first to start working on it together with union feature. You are free to continue, if you want, but we are working with @Angelelz for some time already and discussing a proper typing and API and I guess we will continue with his work. We would also appreciate if you can help him in his part of work as well!

I think we should go back to assigning issues/features. Since we're receiving a lor more PRs than before.
I'm happy to assign a couple to me like we discussed over at discord.

@AndriiSherman, all good! I really want to contribute to this project so I'll pick up another issue, should I close out this PR?
