The oneApi support has bit rotten since it was first introduced. Update the support to function with the latest 2023.0.0 release and add a check to only support that version or newer for now. Versions before 2021.2.0 have linker script failures. Various fixes made: * In the 2023.0.0 release, various binaries are in a llvm-bin path so add support to search in that path. This replaces the python search path that much older versions needed. * newlib isn't supported with oneApi so set TOOLCHAIN_HAS_NEWLIB to OFF to match that. * 2023.0.0 doesn't back llvm-nm, so use binutils version. This is expected to be fixed in 2023.1.0 release so add a check to handle either case. * Update compiler flag check based on clang to also support CMAKE_C_COMPILER_ID of "IntelLLVM" as that is how the oneApi toolchain reports itself.
