Flip --incompatible_windows_escape_python_args

    CI test results (Bazel@HEAD + Downstream):
    https://buildkite.com/bazel/bazel-at-head-plus-downstream/builds/1003

    The flag affects Windows only, and on Windows only
    two projects are broken: rules_foreign_cc and
    rules_nodejs.

    These are also broken on other platforms, and in
    the previous build:
    https://buildkite.com/bazel/bazel-at-head-plus-downstream/builds/1002

    Therefore I'm reasonably sure they are not broken
    by this PR. That said, we can't completely be
    sure because the tests didn't run.

    See bazelbuild/bazel#7974
