Add API.last_error #55

Because Ruby may call Win32 API and reset the error code before a user calls GetLastError(), the user might not be able to correct error code. To avoid it win32-api should store last error code like FFI or Fiddle do it. FYI:

FFI::LastError.winapi_error https://www.rubydoc.info/github/ffi/ffi/FFI/LastError#winapi_error-class_method
Fiddle.win32_last_error https://rubyapi.org/3.0/o/fiddle#method-c-win32_last_error
