Rollup merge of rust-lang#114070 - blyxyas:iter_mut_symbol, r=oli-obk

Add `sym::iter_mut` + `sym::as_mut_ptr` for Clippy

We currently have `sym::iter` and `sym::iter_repeat`, this PR adds `sym::iter_mut` as it's useful for rust-lang/rust-clippy#11038 and another Clippy lint, it also adds `sym::as_mut_ptr` as it's useful for rust-lang/rust-clippy#10962.
