Fix test_libtorch.bat not exiting on error (#109393)

For some weird reason, the batch file gets rid of the `exit /b 1` inside the for loop, so failures never actually get surfaced.  Add skips for the tests that were failing.
Also don't run the windows cpu build on main since it's in trunk.  This is what currently works for the rocm build.

The temp file failure originates from #108508 (got fixed before I merged this PR)

I'm not sure when the ChunkRecordIteratorTest started failing, but it was after the above.
