Runs every measurement-cleanup callback registered via
registerMeasurementCleanup and clears the measurement HTML overlay
layer on the given view. Shared between the user-facing
AcApClearMeasurementsCmd command and internal lifecycle hooks
(e.g. clearing measurements when the user switches paper-space
layouts, where any pending measurement would otherwise leak across
layouts in coordinates that no longer make sense).
