[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.
NVIDIA is unaffected because its version string ("7.5" style) has no ':'
to truncate. Take a std::string_view in the helper and pass the bounded
substring so the comparison respects the truncation.
