Cycles: Distinguish Apple GPUs by core count

This patch suffixes Apple GPU device names with `(GPU - # cores)` so that variant GPUs with the same chipset can be distinguished. Currently benchmark scores for these M1 family GPUs are being incorrectly merged:

- M1: 7 or 8 cores
- M1 Pro: 14 or 16 cores
- M1 Max: 24 or 32 cores
- M1 Ultra: 48 or 64 cores
