[CI] Use oneAPI for Windows postcommit builds (#16355)

Getting this working was an unbelievable amount of work. I hit so many weird issues caused by dumb Windows things (case insensitivity, cmd vs bash, bugs in cmake/ninja/sccache themselves) but finally I got something that consistently passes. You can see the funniest dumb Windows issue in the comment in the CMake file change. The basic idea is to extend the Windows build workflow to allow using `icx`, add an action to setup the oneAPI environment, call it from the build action and the test action (since we need some of the shared libs on path even for testing), and fix some oneAPI-only build issues. We need to do some Powershell magic after calling the oneAPI setup bat script because the environment variables get lost since it's run in a subprocess. We also switch to `ccache` instead of `sccache`, because `sccache` doesn't support `icx` (actually neither does `ccache`, but I added it upstream [here](ccache/ccache#1533) and we are using a local build of `ccache`, it was easier to add support to `ccache`). Manually tested it to confirmed cache reads and write are working as expected. At some point we should probably investigate why some tests fail or some compiler flags are required with `icx` only and not `cl`, but let's do that as separate work because I am done with Windows for now. I already set up all Windows runners used here to work with this change. Next I'll add oneAPI builds on Linux, which I really hope is easier. --------- Signed-off-by: Sarnie, Nick <[email protected]>
