This cleans up the fairly arbitrary Windows includes and types and unused functions from the common code and replaces them with platform independent equivalents, or platform specific implementations in common_utils. This removes the Windows 8 support to avoid adding an additional platform function to query this. OBS only supports Windows 10 officially, so it's about time we removed it.
