x11/libxkbcommon: Update to 0.10

Update x11/libxkbcommon to 0.10
Switch to use the meson buildsystem, since the autotools buildsystem has
been removed.
Drop USES=xorg-cat until it supports the meson build system.
Add DIST_SUBDIR and USES=pkgconfig to mimic USES=xorg-cat.
This release does not build and install the static libraries, but they seem
not to be used by any consumer (in the ports tree) anyway.

Note that while it looks like wayland support is disabled, it is just a
test, tests/interactive-wayland.c that's not built. This test isn't
installed even in the case it's built.
libxkbcommon is mainly used by Wayland consumers.
