[Feature Request] Sponsor Portal

Not really, I'm just lazy

Describe the solution you'd like
I would like a sponsor portal(invitation only) where sponsors can register, I can collect information about attendees and companies.

This will likely need to be a more in-depth feature, as it will require many DB changes, and Admin portal updates(being able to update which companies are sponsors)

Additionally, Gatekeeper bot will need to be updated to give sponsor roles out.
