[SYCL] Fix AMD GPU architecture detection (#22670)
get_architecture() stripped the feature-suffix (e.g. ":sramecc+:xnack-")
from the device version string using string_view::substr, but then
passed the view's .data() to a helper taking a const char*. Since
.data() points into the original, non-truncated buffer, the lookup
compared against the full "gfx942:sramecc+:xnack-" string and never
matched, yielding architecture::unknown for AMD GPUs whose gcnArchName
carries feature flags.
