Support Linux aarch64.

[AnarchyMob]

Hello. Is it possible to enable support for the Linux platform on the aarch64 architecture?

/cc @grendello it seems like we would already have this?

We have a Microsoft.Android.Sdk.Linux pack that runs on ~most Linux?

[grendello]

Yeah, it should be possible to do that. I'll set up a build environment on RPI5 and open a PR when ready.

So, I tested that the builds work just fine on an arm64 Linux device, but I have to figure out how to build it on CI for packaging and testing.

The SDK package for Linux arm64 is not working. All native binaries inside the SDK were built for the Linux x86_64 architecture, including libZipSharp, libMono.Unix and Binutils.
