In cg_gcc ModuleBuffer already only contains a path anyway. And for moving LTO into -Zlink-only we will need to serialize MaybeLtoModules. By storing a path cached modules we avoid writing them to the disk a second time during serialization of MaybeLtoModules.

Rollup merge of #155036 - bjorn3:lto_refactors16, r=TaKO8Ki Store a PathBuf rather than SerializedModule for cached modules In cg_gcc `ModuleBuffer` already only contains a path anyway. And for moving LTO into `-Zlink-only` we will need to serialize `MaybeLtoModules`. By storing a path cached modules we avoid writing them to the disk a second time during serialization of `MaybeLtoModules`. Some further improvements will require changes to cg_gcc that I would prefer landing in the cg_gcc repo to actually test the LTO changes in CI. Part of rust-lang/compiler-team#908
