Add support for attaching to native arm64 on macOS

[CCP-Lease]

This is a fix for #200

Now that I think about it, a pull request with a random binary file probably isn't a good idea.

Maybe I should remove the dylib and just have the text file changes instead?

Hello, I actually just merged something related:

See the description at: c4774a9

With that you can locally compile and use it, but there are still no plans to officially support it out of the box (I can't really accept a blob with the pre-compiled binaries and even after having it compiled, at the minimum it must also be tested on the ci in this case if it'll be supported out of the box).

I do have plans to improve that situation as a whole in the future (ideally all binaries would be compiled in the ci and when packaging it'd be possible to download all the related binaries to do a bundle supporting multiple platforms to distribute for some IDE) -- albeit that's a bigger item (I do accept pull requests to make that work if you're interested, but keep in mind that this is a bigger item, which is definitely more time-consuming).

@fabioz How would I go about compiling an attach_linux_arm64.so? I'm using an M1 mac but running the application in an arm64 docker image. I'm not very familiar with cross compiling, or even the right flags I would use. Any help would be appreciated!

edit: I believe I figured it all out. Having separate issues, but was able to successfully load in the lib
