Уменьшение задержки!!! - #66

The UI file (cui/uiconfig/ui/optuserpage.ui) contains
a "cryptography" GtkFrame, with an internal GtkLabel
child that has the ID "cryptographylabel".

Use the weld::Frame API to get the label and don't rely
on a weld::Label existing for the internal child.

The latter doesn't exist for the case of using native
Qt widgets (qt6 vcl plugin with
SAL_VCL_QT_USE_WELDED_WIDGETS=1) where the QGroupBox
widget used in QtInstanceFrame handles the label
itself, without a separate child widget.

This fixes a crash/assert seen for the following scenario
with the qt6 vcl plugin and SAL_VCL_QT_USE_WELDED_WIDGETS=1:

* start Writer
* "Tools" -> "Options"
* type anything in the search box

Assertion and backtrace:

    soffice.bin: /home/michi/development/git/libreoffice/vcl/inc/qt6/../qt5/QtBuilder.hxx:125: T *QtBuilder::get(const OUString &) [T = QLabel]: Assertion `!pWidget || qobject_cast<T*>(pWidget)' failed.
