Include optional dso_local marker for functions in `enum-match.rs`

This PR adds the `dso_local` marker to the `enum-match.rs` test annotations for all the `match\d+` functions. These markers are added by LLVM when targeting `aarch64-unknown-none` even though they are missing in `aarch64-unknown-linux-gnu`. This is causing a CI error when running the codegen suite on the `aarch64-unknown-none` target for ferrocene.
