This is part of the SYCL support upstreaming effort. The relevant RFCs can be found here: https://discourse.llvm.org/t/rfc-add-full-support-for-the-sycl-programming-model/74080 https://discourse.llvm.org/t/rfc-sycl-runtime-upstreaming/74479 The SYCL runtime is device-agnostic and uses liboffload for offloading to GPU. This commit adds a dependency on liboffload, implementation of platform::get_platforms, platform::get_backend and platform::get_info methods, initial implementation of sycl-ls tool for manual testing of added functionality. Plan for next PR: device/context impl, rest of platform test infrastructure (depends on L0 liboffload plugin CI, our effort is joined) ABI tests --------- Signed-off-by: Tikhomirova, Kseniya <kseniya.tikhomirova@intel.com>
