Rollup merge of #134300 - RalfJung:remove-dead-attrs, r=chenyukang

remove long-deprecated no-op attributes no_start and crate_id

These have emitted a deprecation warning since forever (https://github.com/rust-lang/rust/pull/64471) and they already don't do anything. In fact they [apparently](https://github.com/rust-lang/rust/pull/64471#issuecomment-531517332) have done nothing since pre-1.0, so... do we even need a crater run? Doesn't seem worth it.
