message: [lldb-suite] Skip TestMachCore on Windows
  This test was originally marked as expected failure on Windows, but it is timing out instead of outright failing now. The expectedFailure attribute does not correctly track timeouts (as in, they don't count as failures), so now this is causing the test suite to fail.
