Change QConnectionSenderSwitcher et al to use signal index range

First step towards getting rid of the signal_absolute_index variable
from QMetaObject::activate() (which requires computation of the
class's method offset).

This also required changing the implementation of the public function
senderSignalIndex() so it still returns an index in the full method
range.
