Debian likes to install qt binaries into an obscure path, search here as well

REVIEW: 122526

While the search is unlikely to succeed on Windows, having different
behaviour between the platforms (eg: find_package(Wayland REQUIRED) was
not fatal on Windows, even though Wayland_FOUND would always be FALSE)
is not ideal, and if someone did port them to Windows for some reason,
the find modules should support that.

If applications actually want different behaviour between platforms
(like requiring a module on Unix, but not on Windows), they should
implement that logic themselves (since they will have to deal with
targets not being defined, etc, anyway).

Add a couple of find modules for wayland-scanner and qtwaylandscanner.
These modules find the respective executables and create a target that
points to the executable.

Targets are respectively Wayland::Scanner and Wayland::QtScanner.

There are also macros to generate C protocols with wayland-scanner and
C++ wrappers with qtwaylandscanner.
