Wayland: Add initial support for libdecor

This is partly based on the implementation of libdecor support in
PR #1693 by @ christianrauch.

Where available, the libdecor library is loaded at init and becomes the
preferred method for window decorations.  On compositors that support
XDG decorations, libdecor in turn uses those.  If not, libdecor has
a plug-in archtecture and may load additional libraries to either use
compositor-specific decorations or draw its own.

If necessary, support for libdecor can be disabled with the
GLFW_WAYLAND_LIBDECOR init hint.  This is mostly in case some part of
the dynamic loading or duplication of header material added here turns
out to cause problems with future versions of libdecor-0.so.0.

Fixes #1639
Closes #1693
Related to #1725

This was adapted to 3.3-stable from
fbdb53b9ca.

GLFW uses the [libdecor library](https://gitlab.freedesktop.org/libdecor/libdecor)
for window decorations, where available. This in turn provides good quality
client-side decorations (drawn by the application) on desktop systems that do
not support server-side decorations (drawn by the window manager). On systems
that do not provide either libdecor or xdg-decoration, very basic window
decorations are provided. These do not include the window title or any caption
buttons.
GLFW uses the [xdg-decoration
protocol](https://cgit.freedesktop.org/wayland/wayland-protocols/tree/unstable/xdg-decoration/xdg-decoration-unstable-v1.xml)
to request decorations to be drawn around its windows. This protocol is part

@subsubsection init_hints_wayland Wayland specific init hints
@anchor GLFW_WAYLAND_LIBDECOR_hint
__GLFW_WAYLAND_LIBDECOR__ specifies whether to use
[libdecor](https://gitlab.freedesktop.org/libdecor/libdecor) for window
decorations where available. Possible values are `GLFW_WAYLAND_PREFER_LIBDECOR`
and `GLFW_WAYLAND_DISABLE_LIBDECOR`. This is ignored on other platforms.
@note This init hint was added in 3.3.9 and is not present in earlier patch releases. It
is safe to attempt to set this hint on earlier versions of GLFW 3.3 but it will emit
a harmless @ref GLFW_INVALID_ENUM error. If you need to avoid causing any errors, you can
check the library version first with @ref glfwGetVersion.
@note To set this hint while also building against earlier versions of GLFW 3.3, you can
use the numerical constants directly.
