feat: properly parse and resolve tuples

[JairusSW]

This PR adds basic support for the Tuples. Roadmap wise, this, along with a few more PRs, will pave the way for the Multi Value Proposal to be properly implemented.

The goal of this PR is not to add full-fledged support for Tuples. Instead, it supports the basic functionality for parsing and resolving them since optimal Tuple implementation relies on Multi Value support.

The order of the PRs to implement are:

1. Parse and resolve tuples
2. Hook up Multi Value support to binaryen
3. Clean up, test, and enable multi-value by default

Speaking of that, all the features here hide behind --enable multi-value

So far, this implements:

• Parser

  • Parameters: function foo(x: [i32, i32]) {}
  • Return types: function foo(): [i32, i32] {}
  • Return values syntax: return [0, 1]
  • Type aliases: type Foo = [i32, i32]
  • Type names: [x: f64, y: f64]

• Compiler

  • Tuple usages error with not implemented (for now)
