Added `mlir/test/Integration/Dialect/XeVM/GPU/xevm_truncf_extf_raw.mlir`. In addition to the round trip, it writes out and checks the raw down-converted f8 (E4M3FN) bytes (e.g. `1.0 → 0x38`, `16.0 → 0x58`) and the up-converted f16 values, so both directions are verified against known constants rather than just round-trip identity.
