feat!: implement core store API in runtime

[aaronc]

Description

This implements the core store API introduced in #14227.

It also removes the bundle Service from core because I'm not sure we're ready to commit to that, see #14326 (comment).

I am honestly not sure how to test this without migrating a module which would be breaking. If I don't break module APIs, this can be safely backported to 0.47 and then we can try it with collections and the circuit breaker module as a proof of concept.

I removed this from core because:

1. we don't have intermodule.Client implemented yet
2. bundling all the store keys together means we need to register all these keys for every module and I don't think that's smart

So let's revisit the idea of a bundle service later to see if it makes sense
