This reverts commit b276acc. This is a follow up to rust-lang#16935 where we take a different direction for false positives. Instead of an allowlist, we will ignore unused direct deps that are also transitive deps (technically still used somewhere). This leaves workflows like `curl` where the `build.rs` dynamically decides what deps to use but that seems like enough of an exception case to not worry about direct integration for.

What does this PR try to resolve?
This is a follow up to #16935 where we take a different direction for false positives.
We are now ignoring unused direct deps that are also transitive deps (technically still used somewhere). This leaves workflows like
curlwhere thebuild.rsdynamically decides what deps to use but that seems like enough of an exception case to not worry about direct integration for.This means we can punt on having an allowlist to decide what approach we want take from among rust-lang/rfcs#3920
