this logic is moved to rustc_attr_parsing/src/feature_gate.rs which gets called from rustc_attr_parsing/src/interface.rs

I don't have time to fully parse everything rn, just a question. If the gate is Gated::Ignore, is the attribute parser still called? i.e. is this code
rust/compiler/rustc_attr_parsing/src/attributes/diagnostic/on_move.rs

This was removed in #155209, this looks like you accidentally resurrected it.

Is Ignore only used for diagnostic attr feature gates? (Please add a comment).
