7e31f2cf - [clang][SYCL] Diagnose reference kernel parameters (#192957)

[clang][SYCL] Diagnose reference kernel parameters (#192957) Per SYCL 2020 spec: Reference types are not trivially copyable, so they may not be passed as kernel parameters. This PR adds infrastructure for kernel object visiting and implements diagnostics for reference kernel parameters. The infrastructure will be also used for other kernel parameter restrictions and functional code transformations that will be done in separate PRs.
