While QtInstanceEntry generally takes care of handling signals
for the spinbox's QLineEdit, this doesn't work when the value
is changed as a result of setting a new spinbox value (e.g.
by using the spinbox buttons), as the QLineEdit signals are blocked
then, see QAbstractSpinBoxPrivate::updateEdit in qtbase [1].
Therefore, connect the QDoubleSpinBox::textChanged signal
to the slot that calls signal_changed() instead to ensure
it gets called nonetheless, and disconnect from the other signal.
While at it, also add a SolarMutexGuard when calling the
signal.
This fixes the issue noticed with the "Go to Page"
dialog mentioned in previous commit

tdf#130857 qt weld: Support "Go to Page" dialog
as:
> One issue seen with the dialog is that by using the
> up arrow of the spinbox to increase the value, it
> is currently possible to increase the value
> beyond the maximum value (last page number),
> while this is not the case when typing a number
> into the box manually.
>
> This is because the GotoPageDlg::PageModifiedHdl
> handler currently only gets called for the
> latter case, not the former one, despite
