E2E tests disabled on CUDA

### Describe the bug

There is a list of E2E tests disabled on CUDA that don't have attached issues.
I'll use this one to track these test:
```
sycl/test-e2e/Assert/assert_in_simultaneous_kernels.cpp
sycl/test-e2e/Assert/assert_in_simultaneously_multiple_tus.cpp
sycl/test-e2e/Basic/gpu_max_wgs_error.cpp
sycl/test-e2e/DeprecatedFeatures/DiscardEvents/discard_events_using_assert.cpp
sycl/test-e2e/DeviceLib/separate_compile_test.cpp
```

### To reproduce

1. Include code snippet as short as possible
2. Specify the command which should be used to compile the program
3. Specify the command which should be used to launch the program
4. Indicate what is wrong and what was expected

### Environment

- OS: [e.g Windows/Linux]
- Target device and vendor: [e.g. Nvidia GPU]
- DPC++ version: [e.g. commit hash or output of `clang++ --version`]
- Dependencies version: [e.g. the output of `nvidia-smi` and `sycl-ls --verbose`]

### Additional context

_No response_

Start with the five listed sycl/test-e2e files and the configuration that disables them on CUDA. Reproduce each failure on a CUDA setup, identify why the tests are disabled, and verify the relevant behavior. Done means the tests pass on CUDA and are no longer disabled.
