[CI] Remove matrix usage in windows tasks (#10918)

We only have single configuration on Windows and Linux has switched not
to use matrix generator earlier. Remove last usage and the matrix
generator infrastructure with it.

This PR also inlines `devops/actions/e2e-tests-win/action.yml` directly
into `.github/workflows/sycl_windows_build_and_test.yml`. I decided not
to outline windows end-to-end task into
`.github/workflow/sycl_windows_run_tests.yml` (unlike Linux) because we
don't use docker images for Windows and can't have one with
pre-installed nightly build. This can be re-visited later.
