Have FLTK use libdecor at version > 0.2.2

Browse Source 
- it's no longer necessary to take care of the change in the layout of "struct libdecor"
between versions ≤ 0.2.2 and > 0.2.2 of libdecor
- version > 0.2.2 contains MR131, that is, it defines LIBDECOR_WINDOW_STATE_RESIZING
so the hack to emulate it is no longer  necessary
- CMake option FLTK_USE_SYSTEM_LIBDECOR now requires libdecor version > 0.2.2
to be activated, otherwise the bundled libdecor is used
- what will be the libdecor version after 0.2.2 (0.2.3? 0.3.0?) is not known as of today

The FLTK Wayland platform uses a library called libdecor which handles window decorations
(i.e., titlebars, shade). On very recent Linux distributions (e.g., Debian trixie)
libdecor is available as Linux packages (libdecor-0-dev and libdecor-0-plugin-1-gtk).
FLTK requires version 0.2.0 of these packages or more.
In other situations, FLTK uses a copy of libdecor bundled in the FLTK source code.
FLTK requires a version > 0.2.2 of these packages that's not yet available.
Therefore, FLTK uses a copy of libdecor bundled in the FLTK source code.
FLTK equipped with libdecor supports both the client-side decoration mode (CSD) and the
server-side decoration mode (SSD) as determined by the active Wayland compositor.
Mutter (gnome's Wayland compositor) and Weston use CSD mode, KWin and Sway use SSD mode.
