[WIP] Port intel pvc

[yasahi-hpc]

In this PR, I have added the SYCL backend support for Intel PVC. Although the tests passed, performance seems quite bad.
For the moment, the CI for Intel does not work since the oneMKL is missing in the container. As well as ginkgo guys, we may rely on spack?

Due to the issue of OpenMP library, oneMKL seems disabled.

CMake Error at common/src/CMakeLists.txt:25 (find_package):
  Found package configuration file:

    /opt/intel/oneapi/mkl/latest/lib/cmake/mkl/MKLConfig.cmake

  but it set MKL_FOUND to FALSE so package "MKL" is considered to be NOT
  FOUND.  Reason given by package:

  The required variable OMP_LIBRARY has an invalid value
  "OMP_LIBRARY-NOTFOUND".
