[Driver][SYCL] Handle invalid characters from device in temp files (#14563)

When using command lines such as -fsycl -fsycl-targets=spir64_gen
--offload-new-driver -Xsycl-target-backend "-device *" there is a
temporary file that is generated that contains the arch value. Eliminate
any possible invalid characters from being used with this temporary
file.
