Dynamic shapes are recorded as tir.Var + IntImm in relax. This PR create MSCPrim to map the PrimNode in tvm to MSC. The MSCPrim can be codegen to different frameworks to support dynamic shapes, such as dynamic batch in training and dynamic dims in LLM.
MSC records the PrimNode and the relations between PrimNodes as MSCPrims in DAG format, so that the dynamic dim can be described (e.g res_0.shape[0]*2) during codegen.
