Using SYCL to generate device kernels is a bad idea

[hdelan]

We have no ABI guarantees for the ordering of kernel args for lambda kernels in SYCL. For a given kernel lambda, it is feasible that different lambda signatures are generated across different versions of the same compiler.

As such we should not use SYCL lambdas to generate device kernels here https://github.com/oneapi-src/unified-runtime/tree/main/test/conformance/device_code

We should use an API where kernel signatures are explicit, like openCL kernel language.
