Add Linux / MacOS versions of static libraries

[BobLd]

Thank you for your work in making Skia's Windows static libraries available, this is incredibly helpful!

I was wondering if there are any plans to provide static library builds for Linux and macOS as well? Having cross-platform static libraries would be valuable in making Avalonia single file apps on other platforms too.

Mac OS does not familiar.
Linux may be usable if it is not depend on glibc.
Most of them, the issue is they don't have a stable ABI.
And may fking crash at runtime on the fly :(

@peaceshi thanks for answering! I'm more interested in Linux. On my side, I have disabled GPU in avalonia, is glibc still needed? I'm only looking for the skiasharp native libs. Keep me posted 😀
