First class stripe integration

[tysonzero]

It seems like this would fit nicely in line with supabase storage and supabase auth: "supabase pay" as a baked in stripe integration that gives you the functionality of stripe-sync-engine plus any other commonly needed convenience functionality beyond that.

I have been considering using stripe-sync-engine as it does seem quite compelling, but the additional benefit vs effort over just sticking with what comes with the nextjs-subscription-payments vercel template makes it unclear if it's worth it, however if it were a first class feature like storage and auth it would clean up a lot of the noise in that template and make various further stripe functionality quite a bit quicker for developers to implement.
