#5222605 Domains: Reduxify wapi-domain-info

This PR reduxifies the wapi-domain-info flux store.

Although it looks a bit large, it’s mostly a simple port of the flux functionality plus some tests. There are a couple of reasons for the PR to look extra large, actually:

• There are a bunch of notices we’re now porting to data layer instead of handling them in the component.
• We’re removing the old store.
• We’re adding some tests.

Changes proposed in this Pull Request

• Domains: Reduxify the awapi-domain-info store.

This PR introduces a new error when accepting a domain transfer fails:

Testing instructions

• Go to /domains/manage/:site/transfer/out/:domain where :site is one of your sites with custom domains, and :domain is the domain.
• Comparing to production, test the transfer functionality from end to end – requesting a transfer code (with unlocking the domain too), resending it, canceling transfer, then proceeding through transferring a domain to another registrar and observing the domain edit screen in the meantime.

Because of my limited understanding of the domains functionality, I’d really appreciate it if I can get this reviewed from @Automattic/cobalt or @aidvu. Thanks 🙌

Fixes #47340.
