[P] - VkFFT now supports Apple Metal API - M1 Pro GPU FFT benchmarking

Hello, I am the creator of the [VkFFT](https://github.com/DTolm/VkFFT) \- GPU Fast Fourier Transform library for Vulkan/CUDA/HIP/OpenCL and Level Zero. In the latest update, I have added support for Apple Metal API, which will allow VkFFT to run natively on modern Apple SoC.

I have tested it on MacBook Pro with an M1 Pro 8c CPU/14c GPU SoC single precision on 1D batched FFT test of all systems from 2 to 4096. Achieved bandwidth is calculated as 2\*system size divided by …
