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

De-duplicate all consecutive native libs regardless of their options

Address https://github.com/rust-lang/rust/pull/126913#issuecomment-2188184011 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`.
