Provide visibility into which (core) field type props can be mapped into Content Type Templates vs not

First full green test run!

To get a list of the remaining work, force XB to pretend we're at 100%:

$ git diff

… and then you'll get explicit test failures:

So, with #6, we've got a way to list the remaining work, to achieve @lauriii's stated goal of supporting ALL core field types + widgets.

It also empowers @lauriii to decide which field types, field type props and field widgets we'll intentionally exclude from scope. (i.e. won't work on adding support for)

It'll get surfaced in a more accessible form in 📌 CI: surface the list of field types, field type props and field widgets not yet supported by XB Active .

Follow-ups, now all linked:

• 📌 Provide visibility into field types with different matching SDC prop shapes depending on field storage settings Active
• 📌 CI: surface the list of field types, field type props and field widgets not yet supported by XB Active
• ✨ Do we want to support the `link` field type's `options` prop? Active
• 📌 Mark two more core field type's computed properties as internal Active
• 🐛 Find bug(s) that explain unmatched field type props Active

And some of the core bugs surfaced here actually have been known for years: I opened 📌 [PP-1] Convert field_storage_config and field_config's form validation logic to validation constraints Postponed in November 2022 😅
