[cmake] Device code can't support STL-internal assertions. Default-off

SYCL_DISABLE_STL_ASSERTIONS=ON

Unless we maintain our own STL for SYCL we can't know the visibility of
the internal assertion mechanism of libstdc++ and friends. This caused
random-looking build failures in device code for which we have no
reliable method of avoision when I adopted gcc12.2.
