Make all backends support Screen() constructor

CHANGELOG.md

 ## [Unreleased]
 
+- Added empty constructor to all backends for `Screen` allowing `display(Makie.current_backend().Screen(), fig)` [#4561](https://github.com/MakieOrg/Makie.jl/pull/4561).
 - Added `subsup` and `left_subsup` functions that offer stacked sub- and superscripts for `rich` text which means this style can be used with arbitrary fonts and is not limited to fonts supported by MathTeXEngine.jl [#4489](https://github.com/MakieOrg/Makie.jl/pull/4489).
 - Added the `jitter_width` and `side_nudge` attributes to the `raincloud` plot definition, so that they can be used as kwargs [#4517]https://github.com/MakieOrg/Makie.jl/pull/4517)
 - Expand PlotList plots to expose their child plots to the legend interface, allowing `axislegend`show plots within PlotSpecs as individual entries. [#4546](https://github.com/MakieOrg/Makie.jl/pull/4546)
