MVKPhysicalDevice: Require Mac family 2 for quad-scope permutation.

Browse Source 
According to the Metal Feature Set Tables, only family 2 supports
quad-scope permutation. We've been seeing issues with SIMD-group
functions on family 1 hardware, so for now I'm moving quad-group
permutation to family 2.
