Add support for stdlibs that were compiled with -Zno-embed-metadata

As of nightly 2026-01-14 the rust stdlib is compiled using -Zno-embed-metadata. This removes the rmeta data from .rlib object files. Fixing this means we need to include the .rmeta files in the stdlib file group. Breaking change in rustc: rust-lang/rust#145343 Context on -Zno-embed-metadata: rust-lang/cargo#15378
