rustc_interface: Add a new query `pre_configure`

It partially expands crate attributes before the main expansion pass (without modifying the crate), and the produced preliminary crate attribute list is used for querying a few attributes that are required very early.

Crate-level cfg attributes on the crate itself are then expanded normally during the main expansion pass, like attributes on any other nodes.
This is a continuation of rust-lang/rust#92473 and one more step to very unstable crate-level proc macro attributes maybe actually working.

Previously crate attributes were pre-configured simultaneously with feature extraction, and then written directly into `ast::Crate`.
