Morph many to one picker (#14155)

This PR follows the multiSelect PR merged previously. It will enable
morph relation Many to One to be handled from the table, using a
singleSelect picker

Main point : I decided to change the singleSelect API to take an array
of **objectMetadataName** instead of only one to deal with both our
usecases.
