Rollup merge of #145781 - Kobzol:clippy-remove-profile, r=lqd

Remove profile section from Clippy

To avoid workspace warnings.

[This](rust-lang/rust#145749) subtree sync started causing warnings in Rust builds (rust-lang/rust#145777) because of the `profile` section in Clippy's `Cargo.toml` file. This profile section was added in rust-lang#13408 last year, and since it also caused issues then, it was later reverted. However, this change recently reappeared in [this commit](rust-lang@90364dd), so it is again causing issues for rust-lang/rust.

This PR removes the profile section again.

Fixes: rust-lang/rust#145777
