Remove subprojects

[kelson42]

Meson subprojects adds a new level of compilation dependencies which makes the overall dependencies understanding even more difficult to understand.

We, at Kiwix, already track the dependencies at kiwix-build level and that should be the unique way to impact the CI/CD compilation of libzim.

For external developers, it has been also usually advocate that the meson subprojects make the life of developers easier. But I think at the end:

• Developers should be able to handle the dependencies anyway
• At the end if complexifies the undestanding because we have an additional level (to the usual local and system libraries)

@veloman-yunkan To me it looks like the kiwix-build CI does not provide the libzma headers and binaries, therefore it fails to compile here on Windows. Would you be able please to confirm?

Confirming. kiwix/kiwix-build@d8b4d24?w=1 didn't include lzma in the list of base dependencies under Windows and it has stayed like that since.
