Shane Ringrose 206c37f620 cmake(qt6): verify Qt6::GuiPrivate at configure time, drop #warning ...

<private/qpdf_p.h> (QPdfEngine::drawHyperlink) needs Qt's private GUI
module, previously flagged only by a #warning at compile time.

Qt >= 6.7 ships GuiPrivate as a proper find_package component, but some
distro packages (e.g. Ubuntu's qt6-base-private-dev, Qt 6.8.3) do not
install Qt6GuiPrivateConfig.cmake and only provide the implicit
Qt6::GuiPrivate target created alongside Qt6::Gui. Requesting the
component unconditionally would therefore break distro-Qt builds.

Instead: try the component quietly, then hard-verify the Qt6::GuiPrivate
target exists after the main find_package, failing at configure time
with an actionable message if the private headers are missing. The
compile-time #warning in pdf_links.cpp and projectprintwindow.cpp is
now redundant and removed.

Verified: cmake configure + compile of both translation units on
Ubuntu 25.04 / Qt 6.8.3 (system KF6), cmake configure on Qt 5.15.
