CoreKiwix.xcframework is the packaging format required by Kiwix apple (macOS/iOS) reader for libkiwix.
Naming will hopefully be revisited later (libkiwix.xcframework?)
This folder is a combination of all static archive (*.a): dependencies and libkiwix itself
for all apple-supported platforms: macOS x86_64, macOS arm64, iOS arm64 and iOS x86_64.
It also includes the headers.
Note: while iOS archs are separated in the framework, the macOS archs are bundled as a fat binary.
This thus adds:
- A new `apple_all_static` target that lists mentioned sub-platforms.
- A new `AppleXCFramework` virtual dependency and builder
- requires `libkiwix`
- merges the archives into one per target
- creates the fat binary for macOS
- creates the xcframework
- `libkiwix_xcframework-VERSION.tar.gz` because platformname is xcframework
- it only contains the xcframework but in libkiwix_xcframework-VERSION/lib folder
Because with this virtual target, there are no other files
- requires a new `xcframework` platform_name in builddef
- subplatforms deps and macOS/iOS _ok files to make_deps_archive

This target fails on the CI because of conflict between the builded
libraries (lzma, libz) and native library.
As they are both for the same arch but with different libc, python tries
to load them and fails.
There is a real bug somewhere in our toolchain but we need to build for
x86_64 musl right now and this is done in `x86-64_musl_mixed` which pass.
So let's remove it for now.
(`x86-64_musl_dyn` fails with the docker image. It is ok with native
(fedora 38) system)
Having the name of the archive define in common is splitting definition
in different files.
The purpose of build_definition is to centralize definition, so move them
there.
`native_desktop` is not a real target_platform. It is workaround to
specify "build only kiwix-desktop on native_dyn".
It was useful, when we need to build kiwix-desktop on a different build
env than the other project (because of packaging constraints).
Now we can build kiwix-desktop and all other projects on the same build
env, we can remove it and build kiwix-desktop with other `native_dyn`.
