Update nightly SYCL setup

[masterleinad]

Kokkos develop now requires oneAPI 2023.0.0 for SYCL. That's why the nightly builds are currently failing, see https://cloud.cees.ornl.gov/jenkins-ci/blue/organizations/jenkins/KokkosKernels/detail/KokkosKernels/770/pipeline/.
This pull request updates the build to use the same setup as kokkos/kokkos#5813.

Rebased on top of develop.

Assuming that you are oK with these changes, there is absolutely no point in running the CI on these changes.
The Jenkinsfile is clearly not used for anything else that the nightly builds.

-- The CXX compiler identification is unknown
CMake Error at CMakeLists.txt:116 (PROJECT):
  The CMAKE_CXX_COMPILER:

    clang++

  is not a full path and was not found in the PATH.

  Tell CMake where to find the compiler by setting either the environment
  variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path
  to the compiler, or to the compiler name if it is in the PATH.

Need to provide the path in the jenkinsfile.
@masterleinad can you take of this please?
