Execute the EP fused SILU kernel with MXFP6 quantization.
Unlike ep.fused_silu.mxfp4 and .mxfp8, which share one body that
switches on elements-per-byte, FP6 needs its own kernel: four codes per
three bytes is a ratio of 4/3, which that integer cannot represent.
output is packed uint8 at three quarters of the hidden size.
FP6_FORMAT selects the element encoding (0 = E2M3, 1 = E3M2). Both
occupy six bits and pack identically, so nothing downstream can recover
it from the bytes -- it must match what the checkpoint declares.
