Feature request: AArch64 (ARM64) Linux support

[joliss]

I'm running a Linux on an ARM64 CPU, and I'm getting the following error:

$ curl -fsSL https://dvm.deno.dev | sh
Unsupported OS + CPU combination: Linux aarch64

The current Deno release does have a deno-aarch64-unknown-linux-gnu.zip build, which runs fine on my machine, so I think it should be possible to support ARM64 Linux.

This is happening on a Parallels Linux VM on a macOS host with Apple Silicon for me. I assume it would also affect anyone running Linux directly on an ARM machine.

If there's anything I can do to help test or debug, please let me know.
