[Target] Add target tags for Apple Silicon GPU

[MasterJH5574]

As we are recently conducting experiments on GPU of Apple Silicon, we find it helpful to introduce the target tag for Apple Silicon GPUs, as specialized Metal targets.

At this moment, we find the size of shared memory per thread block, the maximum number of threads per thread block and the warp size useful, so each specialized chip is configured by these three parameters.

The feature numbers come from Apple's official document: https://developer.apple.com/metal/Metal-Feature-Set-Tables.pdf
