Importing API types pulls in lots of dependencies

[killianmuldoon]

Inspired by kubernetes-sigs/cluster-api#9011

We should mirror the work to reduce the number of dependencies brought in from importing API types that has been done in the core Cluster API repository at kubernetes-sigs/cluster-api#9011

This will require:

• Moving webhooks out of the API packages
• Dropping controller-runtime/pkg/scheme in the API packages

@laozc Please take a look at the linked issue for context. It should ~ come down to something like this:

• 🌱 Remove reliance on controller-runtime scheme builder cluster-api#9045
• 🌱 Move API v1beta1 webhooks to a separate package cluster-api#9047

We already have consensus on how to do #9045. I'll try to review #9047 soon so we have an established pattern to follow

Can you assign the issue to yourself? Unfortunately I can't do it > #2159 (comment)

@laozc If you have time, the next thing we can do is the equivalent of kubernetes-sigs/cluster-api#9047

Maybe just do it for one webhook first to get a first review and then we can do the same for all

Thx @laozc. I think the only remaining part is "Add import-boss to prevent regressions" (xref: kubernetes-sigs/cluster-api#9011 (comment))

If you have some time, I think we can already explore how to use it in CAPV without waiting for CAPI.
