EdgeIR Operator support for the U55 backend

This list contains operators with silicon acceleration support. The ExecuTorch portable kernels allow running more operations with a fallback. 8x8 designates 8-bit activation and 8-bit weight. 16x8 means 16-bit activation and 8-bit weight. Per-tensor and per-channel quantization are supported.
