[DLE2025.2] Fix warning: ext_oneapi_get_default_context is deprecated: use khr_get_default_context() instead (#4973)

Locally on subset tests - works. CI is still not successful for some
reason: #4963

~The implementation in PyTorch gives confidence in these changes
https://github.com/pytorch/pytorch/blob/06c7516994d6fdd4b1ac8b8aeae74cdcae0d34f4/c10/xpu/XPUFunctions.cpp#L138~

**UPD:** Pytorch approach doesn't suit us, they define the version
`SYCL_COMPILER_VERSION` in
https://github.com/pytorch/pytorch/blob/2a70d98abf8256d3d768eff028fca20198579824/cmake/Modules/FindSYCLToolkit.cmake#L60,
using `icpx --version`. Since `icpx` is not always available to us, we
will have to use the sycl version, which is defined directly in
`sycl/version.cpp` header (however, the version must be determined
carefully, since it does not match the version Pytorch uses).

For example:
2025.2.0
```cpp
// from sycl/version.hpp
#define __SYCL_COMPILER_VERSION 20250604
#define __LIBSYCL_MAJOR_VERSION 8
#define __LIBSYCL_MINOR_VERSION 0
#define __LIBSYCL_PATCH_VERSION 0
```
```bash
icpx --version
Intel(R) oneAPI DPC++/C++ Compiler 2025.2.0 (2025.2.0.20250605)
```

vs

2025.1.1
```cpp
// from sycl/version.hpp
#define __SYCL_COMPILER_VERSION 20250418
#define __LIBSYCL_MAJOR_VERSION 8
#define __LIBSYCL_MINOR_VERSION 0
#define __LIBSYCL_PATCH_VERSION 0
```
```bash
icpx --version
Intel(R) oneAPI DPC++/C++ Compiler 2025.1.1 (2025.1.1.20250418)
```

Candidate for cherry-pick.
