Re-quantize models in FP16 in keep positional encoding in FP32 to avoid bad accuracy

Apply constant folding

Reperform shape inference on all models

Bugfix: correct batch dimension fixation then regenerate ONNX models

Fix FP16 models having poor accuracy

Make ONNX models compatible with ONNXruntime's TensorrtExecutionProvider

RTMO ONNX Models from MMPOSE range from Tiny to Large
