Add native support for Apple Silicon

[Logicer16]

Current behaviour

Arduino CLI runs under Rosetta 2 on Apple Silicon. While this works at the moment, it is more efficient (and will eventually be required) to run a native version.

Expected behaviour

Arduino CLI should have a native Apple Silicon version.

Environment

• CLI version (output of arduino-cli version): arduino-cli alpha Version: nightly-20210610 Commit: 16f41352 Date: 2021-06-10T01:26:29Z
• OS and platform (theoretically): macOS Big Sur 11.5 Public Beta 2, M1 Mac mini

It looks like Homebrew is already building this for arm64

Given, Homebrew might already be building many packages itself, but not everyone is going to have Homebrew installed. I probably should have specificified that the prebuilt binary, in particular, is an intel build, rather than being a universal build or having a different download for Apple Silicon.

Cause of the missing native support, the "normal" 'make setup' of Kaleidoscope fails:

$ make setup

Thanks for the hint with Homebrew.
