The code LGTM, but I don't know the rational behind it so it's hard to comment on that.

One thing to notice is that we move away form (previously defined) error code PI_ERROR_INVALID_DEVICE, but again, that might be OK, depending on the rationale behind the change.

sycl::exception subclasses (like sycl::runtime_error) are SYCL 1.2 features and have been removed in SYCL 2020. As for the error code, I don't think it's right to create a PI error code out of thin air when it didn't come from the PI level.
