This commit adds a new link overload under the experimental namespace taking a compile-time property list. With this, a new property is added for enabling fast-linking, i.e. linking allowing AOT binaries in a SYCLBIN-based kernel bundle together with JIT binaries. These are all added as part of the sycl_ext_oneapi_syclbin extension. Signed-off-by: Larsen, Steffen <[email protected]>

I think it would be better to add these overloads of link to the sycl_ext_oneapi_kernel_compiler instead. That way, all the new overloads of build, compile, and link taking a PropertyList will be together in one extension. Do you see a downside to that?

| This property instructs the `link` operation to do "fast linking". Enabling this | ||
| instructs the implementation to use device binary images that have been | ||
| pre-compiled. |

I'd add another couple of sentences explaining the tradeoff:
Fast linking trades off potentially slower kernel code for faster link times. When doing normal linking, the compiler may be able to optimize across calls from one bundle to another, but this is not possible when doing fast linking.
