[IMP] web: list: allow to add decorations on field nodes

In list views, one can specify decoration-XXX attributes on the
arch root node. Those decorations are evaluated for each record,
and the corresponding style is applied on rows for which the
condition is true.

This commit allows to specify those decoration-XXX attributes on
field nodes as well. In this case, when the condition is met by a
record, only the field on which the attribute is set will be
impacted.
