fix(ivy): ensure binding ordering doesn't mess up when a `NO_CHANGE` value is encountered (#32143) 

Prior to this fix if a `NO_CHANGE` value was assigned to a binding, or
an interpolation value rendererd a `NO_CHANGE` value, then the presence
of that value would cause the internal counter index values to not
increment properly. This patch ensures that this doesn't happen and
that the counter/bitmask values update accordingly.
