7.0: Remove remaining deprecated Plone 5 resource registry records.

[thet]

This PR targets the yet-not-started Plone 7.0 release and cleans up resource registry records.

It's basically the same like in #363 which was reverted in #364 and saved for future use in this PR. This one has also the fix that plone.resources.development isn't deleted.

A precondition for that is also to clean up and remove the deprecated IBundleRegistry attributes and while at it also the IResourceRegistry interface from plone.base: https://github.com/plone/plone.base/blob/main/src/plone/base/interfaces/resources.py#L91

@thet thanks for creating this Pull Request and helping to improve Plone!

TL;DR: Finish pushing changes, pass all other checks, then paste a comment:

@jenkins-plone-org please run jobs

To ensure that these changes do not break other parts of Plone, the Plone test suite matrix needs to pass, but it takes 30-60 min. Other CI checks are usually much faster and the Plone Jenkins resources are limited, so when done pushing changes and all other checks pass either start all Jenkins PR jobs yourself, or simply add the comment above in this PR to start all the jobs automatically.

Happy hacking!
