Consider using Zig as a C/C++ compiler to enable cross-compilation scenarios

[alexrp]

I noticed that DNNE doesn't currently support cross-compilation for all the usual reasons that cross-compilation is a nightmare.

The Zig compiler supports cross-compilation out of the box across a wide range of platforms, and it contains an embedded Clang along with libc headers and/or sources for many platforms, allowing you to use zig cc/zig c++ as a C/C++ compiler. Cross-compilation basically Just Works. This is one of the reasons I developed my Zig SDK project.

It seems to me that using the Zig compiler as a C/C++ compiler for DNNE would be a ~perfect fit.

(FWIW, if this seems like a sensible thing to do, you could make use of the Zig toolset packages I publish on NuGet with every Zig release.)

@alexrp Thanks for pointing this out. I will definitely look into how it could be used as an option.
