Mac M Series Support

Feature Request
I would like to see this library support M Series ARM based Macs. Since .Net is cross platform it would be great to be able to use this library with native GPU support for the mac platform.

@seanpmac Thank you very much for your feature request and welcome to the ILGPU community. We are currently working on a new high-performance CPU software-implementation to execute all kernels in an efficient way on the CPU. This accelerator can also be used on the M1 Macs. Due to the fact that we have to build a new backend code generator to support the M1 GPUs natively via the Metal interface, a possibility would be to use the currently planned SPIR-V backend via MoltenVK (or a different emulation layer) until a specialized backend is available. Although, we currently do not have an M1 backend on our our roadmap, it might be definitely interesting and also beneficial to implement (given the performance of the upcoming GPUs) @MoFtZ @kilngod

Also support for unified and integrated memory for both M1 and processors with integrated graphics.
