After significant problems in our downstream with the previous implementation, the SYCL standard has opted to make using macros/etc to change kernel-naming-lambdas in any way UB (even passively). As a result, we are able to just emit the itanium mangling. However, this DOES require a little work in the CXXABI, as the microsoft and itanium mangler use different numbering schemes for lambdas. This patch adds a pair of mangling contexts that use the normal 'itanium' mangling strategy to fill in the "DeviceManglingNumber" used previously by CUDA.
