Wayland: Add SDL_HINT_VIDEO_WAYLAND_PREFER_LIBDECOR

Browse source 
This hint allows libdecor to be used even when xdg-decoration is
available. It's mostly useful for debugging libdecor, but could in
theory be used by applications which want to (for example) bundle their
own libdecor plugins.

/**
* \brief A variable controlling whether the libdecor Wayland backend is preferred over native decrations.
*
* When this hint is set, libdecor will be used to provide window decorations, even if xdg-decoration is
* available. (Note that, by default, libdecor will use xdg-decoration itself if available).
*
* This variable can be set to the following values:
* "0" - libdecor is enabled only if server-side decorations are unavailable.
* "1" - libdecor is always enabled if available.
*
* libdecor is used over xdg-shell when xdg-decoration protocol is unavailable.
