[Buildroot] [PATCH v4 24/29] package/qt6/qt6base: add support for gui module widgets/opengl/graphics backends

[Jesse Van Gavere <jesseevg@gmail.com>]

This is a rather large patch as most of these options interact with each
other one way or another, so it's very difficult to split it much
further into sensible patches that still work
