[EPIC] wasmCloud OTP Platform Support

[rvolosatovs]

First, a note: static builds are not supported by Erlang at all. It is not possible to statically-link Erlang OTP, therefore static builds are technically impossible today if we keep using OTP.
Static builds would only be possible if we used an alternative Erlang implementation to compile wasmcloud-otp, e.g. https://github.com/GetFirefly/firefly , which is experimental and does not have good support for Elixir yet

In #616 (comment) we get artifacts with minimum possible amount of dependencies (NOTE, that e.g. Musl self-extracting binary is, indeed, statically-linked, but the actual executables are not, and cannot be, as outlined above), that is:

• MacOS: none
• Ubuntu/Debian:
  • ca-certificates - self-explanatory
• Alpine:
  • libgcc - that's actually a NIF dependency, which is added by the Rust compiler rust-lang/rust#82521
• Windows: none

GNU build is compatible with Ubuntu 20.04 the earliest

All of these builds are produced by CI (including the Erlang distribution). MacOS ERTS are available pre-built at https://github.com/rvolosatovs/otp/releases/tag/OTP-25.3.2, the rest are automatically built if necessary, but in overwhelming majority of cases it should be fetched from cache

#616 is addressing many of these, just keep an eye out

For all intents and purposes, I think we have a great set of platforms here. I'm going to add the pinned label so that it won't get cleaned up by our stale issue bot and leave it as a good piece of information.
