macOS arm64 support and various other fixes

[dpogue]

By default this will make a macOS universal build (with both x86_64 and arm64 in the same files) but supports per-architecture builds using the CMake PX_OUTPUT_ARCH flag.

Building this for ARM64/macOS and getting the following error:

/Users/colincornaby/Documents/Plasma/PlasmaSrc/vcpkg/buildtrees/physx/src/be49a99479-d1b16eed08.clean/physx/source/foundation/include/unix/neon/PsUnixNeonInlineAoS.h:3582:10: error: argument value 2 is outside the valid range [0, 1]
                return vdupq_lane_f32(vget_low_f32(a), index);

The code looks like this:

#if PX_UWP
    if(index == 0)
    {
        return vdupq_lane_f32(vget_low_f32(a), 0);
    }
    else if (index == 1)
    {
        return vdupq_lane_f32(vget_low_f32(a), 1);
    }
#else
    if(index < 2)
    {
        return vdupq_lane_f32(vget_low_f32(a), index);
    }
#endif

The issue could probably be resolved by opting in to the UWP behavior. I'm not sure what the source of this issue is - it should be happening for iOS as well. It could be that Apple has added this enforcement in a compiler update at some point.

I remember seeing this somewhere, but do not recall how I worked around it and why it didn't block submitting this patch (or the acceptance of this patch into other packaging systems) 😕

This patch fixes compilation error.
