Native compiler for Apple Silicon

[gas1cent]

Description

Starting from v0.8.24, solc binaries for macos have become compatible with Apple Silicon chips. It would be very nice to add support for them at some point.

Greetings.

On one hand - there are WASM builds, that should run fine, aside from native. On the other hand, if we would like to support this, we need to change something in following lines:

https://github.com/Consensys/solc-typed-ast/blob/9a70060c2eef771d80790f90a9b37e611fb28721/src/compile/kinds/md.ts#L7-L32

Following logic of downloading proper compiler should work as intended:

https://github.com/Consensys/solc-typed-ast/blob/9a70060c2eef771d80790f90a9b37e611fb28721/src/compile/kinds/compiler.ts#L96-L193

Running

# Locate cache with downloaded compilers:
sol-ast-compile --locate-compiler-cache

# Pre-download native compilers:
sol-ast-compile --download-compilers native

Should result downloading of proper compilers for the current platform.

Some very basic requirement is to successfully compile empty contract with native compiler:

echo 'contract Test {}' | sol-ast-compile --stdin --compiler-kind native --mode sol --tree

SourceUnit #2 -> stdin
|   ContractDefinition #1 -> contract Test

Also we do not run tests against multiple platforms due to our time and resourse constraints. I also do not have Silicon-based hardware in my reach.
