Examples fail to build with AdaptiveCpp

[hjabird]

Summary

Enabling examples causes compilation failures when using AdaptiveCpp.

Version

oneMKL 231aee3 (tip on 05.06.2024).

Environment

AdaptiveCpp v24.02.0
oneMKL 231aee3 (tip on 05.06.2024).

Steps to reproduce

 cmake ../onemkl/ -GNinja -DCMAKE_CXX_COMPILER=clang++ -DONEMKL_SYCL_IMPLEMENTATION=hipSYCL -DENABLE_MKLCPU_BACKEND=OFF -DENABLE_MKLGPU_BACKEND=OFF -DENABLE_ROCRAND_BACKEND=ON -DENABLE_ROCBLAS_BACKEND=ON -DBUILD_FUNCTIONAL_TESTS=OFF -DBUILD_EXAMPLES=ON -DhipSYCL_DIR=/path/to/adaptivecpp/install/lib/cmake/hipSYCL/ -DHIPSYCL_TARGETS=hip:gfx90a

ninja

Observed behavior

Failures due to the use of SYCL-2020 decorated multi-ptrs.

Expected behavior

Examples should compile without errors.
