[SYCL][E2E] Align use of features in tests

Is your feature request related to a problem? Please describe

We've discovered few duplications in #16019:

• windows and system-windows https://llvm.org/docs/CommandGuide/lit.html#default-features
• level_zero and level-zero - not sure which one should be used, there are only 2 uses of level-zero, the rest of tests uses level_zero, but it looks like both options are valid.
