[SYCL][CUDA] LIT XFAIL/UNSUPPORTED

Remove XFAIL from passing tests.

Change tests that should pass but fail as XFAIL, e.g., mark
unexpectedly failing sub-buffer test to fix later for SYCL CUDA.

Add `REQUIRES: opencl` for LIT tests requiring OpenCL.
LIT tests that `REQUIRES: opencl` do not need an `UNSUPPORTED: cuda`.

Mark tests of features not supported by SYCL CUDA with
`UNSUPPORTED: cuda`.

Tests that do not use the CUDA target triple do not require any
CUDA related LIT marker.

Tests that do not fail with CUDA do not require any CUDA specific
LIT marker.

Fix LIT test using `-Werror` to fail when the compiler driver warns
about an unknown CUDA version as CUDA has otherwise nothing to do with
the test.

Adapt test to moved `pi_cuda.hpp` header.

Some cleanup inside LIT configuration scripts.
