ci: enable sccache's GHA preprocessor cache in Linux wheel builds
rapidsai/sccache can store preprocessor-cache entries in the GHA cache alongside object entries. A preprocessor hit skips running the preprocessor, which the object cache alone always has to do to compute its key. The two preceding commits make the compile commands and the generated sources stable across isolated builds, so these entries can now hit.
