[hal] Refactor C++ handle closing; check for invalid handle before closing (#7016)
Adds a close function pointer template parameter to hal::Handle. This allows default destructors in many places. The status parameter has been removed from close functions; in most places it was not used. Where it was, an error is printed instead.
