Right now, oneCCL requires the closed-source Intel SYCL Compiler (Intel® oneAPI DPC++/C++ Compiler) for SYCL support, however we also productize the open-source version of the compiler and it is pretty much feature-equivalent for SYCL, so support using that as well.

The motivation for this change is Canonical is working to package Intel tools for Ubuntu and they do not want to use the closed source products, so their compiler package will be based on the open source SYCL compiler. They want to package oneCCL as well, so this change is required so they can build oneCCL.

I tested this with the currently in-development version of the open source compiler as well as the latest release (6.3.0).

Closes: #191
