[IMP] web: support disable_multiple_selection parameter when opening the o2m dialog

PURPOSE

Sometimes we want to limit selection of 2many fields to a single record at
a time. For example when creating marketing automation activities we want
users to create them one at a time to ease linking between them (parent /
children relationships). Indeed 2many subrecords have to be created before being
selected in other 2many subrecords (i.e. create an activity to set it as
parent of another activity).

SPECIFICATIONS

The open_one2many_record trigger method now accets disable_multiple_selection
option in parameter to pass it to the FormViewDialog constructor.
