        tdf#130857 VclBuilder: Extract setMnemonicWidget helper + call from base

, implement handling for mnemonic widgets for labels
for native Qt widgets in QtBuilder:

* call BuilderBase::extractMnemonicWidget when processing
  a "GtkLabel" object, in the same way that VclBuilder
  does that.

* implement actually setting the mnemonic widget by calling
  QLabel::setBuddy [1] in QtBuilder::setMnemonicWidget to
  set the "buddy" (mnemonic widget)

This makes Orca in a WIP branch to support a native qt6
"Alt Text" dialog announce the label text as well when
the corresponding QLineEdit/QPlainTextEdit receives
focus, as setting the buddy also ensures that the
accessible labelledy-by/label-for relations get
reported on the AT-SPI layer, see also

        tdf#119931: cui a11y: Specify mnenomic-widget in "Alt Text" dialog

which describes the scenario a bit more for the gtk3
variant.
