[BUG]: assert on WIndows is causing hangs with hipcc/hiprtc and errors with hiprtc

Type of Bug

Runtime Error

Describe the bug

When executing the runfail assert tests, I am seeing hangs and timeouts. With hiprtc it seems that wassert does not reliably kill the process. Further investigation is required to debug and solve this issue.

How to Reproduce

lit -vv test/libcxx/asserts/assert_device.runfail.cpp (after cmake configure)

This happens on gfx1151 with hipcc. For hiprtc the tests fails as the assertion does not fail the test (wassert is apparently not failing the test with hiprtc).

Expected behavior

Passing test without hangs.

Operating System

Windows

We will unsupport the affected tests on Windows for now.
