Enable bzip2, lzma and use zlib-ng in a single DSO

[grendello]

Tree layout changes:

• Sources moved from the root dir to LibZipSharp/
• Native builds now happen in lzsbuild and artifacts

Build process changes:

• New Unix script added, build.sh (run build.sh --help)
• CMakeLists.txt added in the root directory to handle all the native builds.
• Apple Silicon support
• Produce fat binaries on macOS
• Linux builds strip debug symbols into a separate file now (packaged in the nuget)
• Windows build script enhanced with better error handling, gained suport for the new cmake build system
• Linux static build patch for libzip no longer needed

Library changes:

• Add submodules for bzip2, lzma and zlib-ng
  • zlib-ng is built in zlib compatibility mode
  • zlib-ng takes advantage of advanced host CPU capabilities (using runtime detection) to speed up (de)compression (ARM, x86)
• All the native code is now built into a single shared library across all the supported platforms, named libZipSharpNative
• Managed code updated to p/invoke into libZipSharpNative
• Added support for the following compression methods:
  • BZIP2
  • XZ (despite the lzma library supporting LZMA and LZMA2 compression algorithms, they are disabled in libzip itself)
• Added tests for the new compression algorithms
• Added new API (Info.GetVersions()) to return version information about all the native libraries + LibZipSharp itself.
