[X] inherit DataType based on attribute (#25173)

Change the heuristic for deciding if we need ot ignore parent DataType,
as DataTrigger.Binding shoud inherit it, and
Picker.ItemDisplayNameBinding should not

this is an alternate fix for #23989, partially replaces #24513, and will
help fixing #25141 together with #24152
