Subject: [PATCH] OptionsCells allowed in Options Interface. Setted field to
 not required in ColumnLayout. (#40302)

OptionsCells: validationFailed were not referenced in any part of index.d.ts. Adding it in Options interface allows the use for tabulator tables (As showed in examples: http://tabulator.info/examples/4.4?#validation)

Field not required in OptionsCells: as commented in old PR field is not required for some type of column (as written in comment: not required in icon/button columns)
