Add support for universal binaries on OSX (#2060)

Browse Source 
When building for multiple architectures on OSX, it's necessary to use
compiler macros to conditionally include architecture-specific code
rather than conditionally including architecture-specific assembly files
via cmake. See
  https://developer.apple.com/documentation/apple-silicon/building-a-universal-macos-binary
and
  https://cmake.org/cmake/help/latest/variable/CMAKE_OSX_ARCHITECTURES.html
for more details.
