[FEATURE] Introduce TCA type "json"

A new TCA type "json" is introduced, which
allows to simplify the configuration when
working with fields, containing JSON data.

It replaces the previously introduced dbtype=json
of TCA type "user" (see: #99226).

FormEngine will display the JSON data using
codemirror, in case EXT:t3editor is installed
and enabled for the field. Otherwise, a standard
textarea HTML element is used.

Using the new type, corresponding database
columns are added automatically.
