Rollup merge of rust-lang#126943 - Urgau:dedup-all, r=petrochenkov

De-duplicate all consecutive native libs regardless of their options

Address rust-lang#126913 (comment) by no longer de-duplicating based on the "options" but by only looking at the generated link args, as to avoid consecutive libs that originated from different native-lib with different options (like `raw-dylib` on Windows) but isn't relevant for `--print=native-static-libs`.
