WIP: aarch64-linux

[alexeymorozov]

Closes #12

[alexeymorozov]

Before merging it should be tested with Alpine to avoid issues like in lutaml/expressir#106.

It's compiled but lacks necessary dependencies to unarchive xar. I think openssl is required for this.

@alexeymorozov Alpine provides a libarchive package: https://pkgs.alpinelinux.org/package/edge/main/x86/libarchive

Perhaps have a look at how they compile it?

[maxirmx]

This is a major rework with three goals in mind:

• fix/implement robust cross compilation scripts to target aarch64-linux-gnu and arm64_apple_darwin for libarchive and previously bundled libraries (zlib, libexpat, libcrypto)
• open a possibility to create x86_64/aarch64-linux-musl native gems
• integrate lzma(7z) support that allows to replace seven_zip_ruby gem in excavate and further drop seven_zip_ruby support

Thank you @maxirmx !
