[BUG] libxkbcommon package is missing compose-data as dependency

[enen92]

Describe the bug

As stated in the documentation for xkbcommon the library relies on the compose files provided by libX11 to be able to handle dead-key and key composing support:

Compose is distributed in libX11, as part of the X locale data.

Support in Kodi was added for wayland in xbmc/xbmc#23943 and is was done for generic libinput in xbmc/xbmc#24044.

To test this I added libx11 as a dependency for libxkcommon:

diff --git a/packages/wayland/libxkbcommon/package.mk b/packages/wayland/libxkbcommon/package.mk

which is obviously wrong since libx11 includes much more than just the compose data. Other distros like debian ship its own package (libx11-data) https://packages.debian.org/bookworm/libx11-data, gentoo with compose-tables (https://packages.gentoo.org/packages/x11-misc/compose-tables), etc.
Also yocto/openembedded have a recipe for libx11-compose-data: https://git.yoctoproject.org/poky/plain/meta/recipes-graphics/xorg-lib/libx11-compose-data_1.8.4.bb.

As far as I can tell libx11 does not provide any way to build only the compose tables. So a possible solution would be to extend the libx11 package (building it) and only actually install the compose files (those in /usr/share/X11/locale/). Since I know nothing about extending existing recipes nor even what the best approach is to handle this, I opted for a bug report.
