[asan] Remove allow_user_segv_handler on Windows.

Summary:
This flags is not covered by tests on Windows and looks like it's implemented
incorrectly. Switching its default breaks some tests.

Taking into account that related handle_segv flag is not supported on Windows
it's safer to remove it until we commit to support it.
