[WIP] std.interface

[alexnask]

This module provides tools to create interface types that work at runtime and comptime.

Checklist:

• std.interface
  • Interface
  • Owned, Comptime, NonOwned, Inline, InlineOrOwned storage types
  • Optional function support
  • Automatic VTable generation
  • VTable generation for any number of arguments (impossible with current language, marking as done)
  • Async function support
  • Tests
  • Proof of concept Allocator reimplementation
  • Async function tests
  • Add documentation

This is currently just a prototype, submitting this PR to make sure the direction of this implementation is something that would fit into zig.

Looks pretty good overall, but i think some doc comments on how to use it would be nice ;)

But: Looks like this could replace the current interface pattern quite well

This looks like a nice project, that is still WIP and does not require any language or std lib changes. My suggestion would be to work on it in a separate repo until it's ready to be proposed to upstream.

I'm sorry I can't answer this question yet. Let's continue discussing in #130. But the open pull request queue is reserved for code that is proposed to get merged into upstream, and this isn't ready for that yet.

@alexnask can you submit a new pull request? I think now it's time to add it to the standard library (see "Related issues" in #10184).
