Provide visibility into which (core) field types (74%), field type props (63%) can be mapped into Content Type Templates vs not, and which field widgets (36%) are supported

First full green test run!

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

EDIT: updated for https://git.drupalcode.org/project/experience_builder/-/merge_requests/7...

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 also allows him to see which props on which (supported) field are not actually supported yet, and make a decision about that — for example the link field's options prop.

It'll get surfaced in a more accessible form in #3512802: CI: surface the list of field types, field type props and field widgets not yet supported by XB.

Follow-ups, now all linked:

• #3512848: Provide visibility into field types with different matching SDC prop shapes depending on field storage settings
• #3512802: CI: surface the list of field types, field type props and field widgets not yet supported by XB
• #3512849: Do we want to support the `link` field type's `options` prop?
• #3512853: Update `FieldInstanceSupportTest` to reflect the shape matching support on October 1, 2025: 100% of core is tracked, 81% of field instance types can be matched, 78% of field instance properties
• #3512854: Determine core bug(s) and missing metadata that explain unmatched field type properties; make the reported % reflect reality

And some of the core bugs surfaced here actually have been known for years: I opened #3324140: Convert field_storage_config and field_config's form validation logic to validation constraints in November 2022 😅
