GH-1876 Fork and update quazip

* It is added as a new submodule: https://github.com/MultiMC/quazip/tree/multimc-1
* Its build system has been entirely replaced to remove the existing issues with it
* It now has working unit tests
* No more patches needed
* It has a static linking exception in its license now, but we use it shared anyway
