The `precalculated_hash` overloads currently exist only on the const lookup functions and `erase`; none of the insertion functions can accept a caller-provided hash. This commit adds `try_emplace_hash()`, `insert_or_assign_hash()` and `insert_hash()` to `robin_map`, and `insert_hash()` to `robin_set`.

tsl::robin_map).
