The namespace declaration for googlehash is a configurable macro that can be disabled. In particular, it is disabled within google, causing compile errors since `dense_hash_map`/`sparse_hash_map` are then in the global namespace instead of in `::google`. Here we play a bit of gynastics to allow for both `google::*_hash_map` and `*_hash_map`, while limiting namespace polution. Symbols within the `::google` namespace are imported into `Eigen::google`. We also remove checks based on `_SPARSE_HASH_MAP_H_`, as this is fragile, and instead require `EIGEN_GOOGLEHASH_SUPPORT` to be defined.
