Merge #6897

6897: Basic support for macros 2.0 r=jonas-schievink a=jonas-schievink

This adds support for (built-in-only) macros 2.0, and removes some hacks used for builtin derives, which are declared via macros 2.0 in libcore.

First steps for https://github.com/rust-analyzer/rust-analyzer/issues/2248.

Blocked on https://github.com/rust-analyzer/ungrammar/pull/16.
