[CI] Enable HIP and CUDA plugins in GitHub Actions builds (#5087)

Build all supported targets as part of the main build step. The idea is to build compiler toolchain once and distribute binary artifacts across machines to run the required testing.

Also this patch adds option to disable some tests, that require real hardware. Those must be moved to intel/llvm-test-suite, as instructed by [contributing guidelines](https://github.com/intel/llvm/blob/sycl/CONTRIBUTING.md).
