meson: configure and use generic exe_wrapper

This replaces the specific gtkdoc wrapper setting
(which was rejected by upstream in https://github.com/mesonbuild/meson/pull/9627)
with a generic, officially supported and documented exe_wrapper,
which is enabled subject to qemu usermode support
(just as is done for g-i and gtk-doc with autotools).

gtk-doc support is adjusted so that this wrapper is passed to
meson's gtk-doc module, which passes it to gtk-doc.

The adjusted patch is re-submitted upstream.

The side effect of this is that meson is now able to run
target binaries in a generic way when it wants to, so this
may affect cross-builds - hopefully in a positive way.

 Make it possible to specify a wrapper for executing binaries
+in cross-compiling scenarios.
 (usually, some kind of target hardware emulator, such as qemu)
