[463456] Repair regressions in InterpretedExpresion property sections

Put back the "implements ContentProposalClient" and the specific
behavior of getFeatureValue for
BorderedStyleDescriptionBorderSizeComputationExpressionPropertySection.

Also add a missing line in the button's listener to call the behavior
when the text is modified.
