[CI][SYCL] Enable E2E testing of NewOffloadModel in SYCL Nightly. (#21167)
This patch reorganizes the matrix of configuration cases for E2E tests
in Linux into the following parts:
1) AMD, NVIDIA and Intel Gen12 GPU cases are extracted in separate job
2) Intel L0 test cases are extracted in separate job
3) OpenCL CPU cases for Intel and AMD are extracted in separate job
4) Test Preview Mode cases are extracted in separate job
Jobs 1-3 are parameterized with enable_new_offload_model - False, True.
Job 4 is not being tested with enable NewOffloadModel.
