Rollup merge of #152188 - cuviper:placeholder-stdarch, r=Mark-Simulacrum

Include `library/stdarch` for `CURRENT_RUSTC_VERSION` updates

Our tool `replace-version-placeholder` uses the `tidy` file walker and its
directory filter, but that skips `library/stdarch` which we do need for public
stability markers. This PR adds a local filter function that explicitly allows
that path.

The commit for 1.94 `stdarch` updates is coming from beta rust-lang/rust#152187.

library/stdarch/crates/core_arch/src/aarch64/neon/generated.rs
