[TASK] Highlight invalid backend layout value

In #89700, the page information view in the info
module was extended for a new type, which displays
the layout related (backend_layout, ..) fields for the
corresponding pages.

Since there might be field values which are not longer
valid, because the referenced backend layout does not
longer exist, the new type does  now highlight such values
with the already known `INVALID VALUE ("<value>")` string.

Resolves: #94674
Releases: master

backend layout, which was previously often difficult. For example in
installations with large page trees and highly developed inheritance.
In case the current field value is invalid, e.g. referencing a non-existent
backend layout, this is now also shown to the editor.
