Gtk3Theme: set XCURSOR_SIZE and XCURSOR_THEME for wayland sessions
GNOME doesn't set these for Wayland session and without those env variables set users might experience broken cursor with Qt apps as QWayland reads them to setup QWaylandInputDevice. There is no cursor protocol available on Wayland yet, see also https://gitlab.freedesktop.org/wayland/wayland-protocols/-/issues/58 Qt Wayland QPA plugin still tries to load from those two envs. Fixes: QTBUG-67579 Fixes: QTBUG-87778 Change-Id: I4e7f6871b56599170b12e796858238b1df6d47d1 Reviewed-by: Liang Qi <liang.qi@qt.io> Reviewed-by: Eskil Abrahamsen Blomfeldt <eskil.abrahamsen-blomfeldt@qt.io> (cherry picked from commit c0b0c7bebb73e1aa609196ce33668a54bd5e0aef) Reviewed-by: Qt Cherry-pick Bot <cherrypick_bot@qt-project.org>
