[Refactor][AST] `sinfo_args` A1: Update API of call_tir, call_packed, etc.

[MasterJH5574]

Following #377 and #379, this PR followups to update the API of call_tir, call_packed, call_builtin and invoke_closure.

• The API of call_tir is changed to

  def call_tir(
    func: Union[str, Expr],
    args: Expr,
    out_sinfo: Union[TensorStructInfo, List[TensorStructInfo]],
    tir_vars: Optional[Union[ShapeExpr, Tuple[PrimExpr], List[PrimExpr]]] = None,
  ) -> Call:
    ...

  where we combine the shape and dtype parameters into out_sinfo. In the concrete CallNode of call_tir, the output shape is no longer passed as an CallNode argument and passed in the sinfo_args instead.

• For call_packed, call_builtin and invoke_closure, we change the type_args parameter to sinfo_args. For example, the API of call_packed is updated to

  def call_packed(
    func: str,
    *args: Expr,
    sinfo_args: Union[StructInfo, List[StructInfo]],
    **kwargs: Any,
  ) -> Call:
    ...

One thing specific to note is about our existing dataflow pattern language. Previously we have a sugar function for call_tir:

def is_call_tir(
    func_name: str,
    args: Union[List, Tuple, TuplePattern] = None,
    shape: Union[Tuple, List[tvm.ir.PrimExpr], DFPattern] = None,
) -> CallPattern:
    ...

Since we changed the API of call_tir - the CallNode does not contain the shape as one argument, - together with the fact that the dataflow pattern language does not yet support matching StructInfo, we have no approach to match the shape anymore. Therefore, the shape parameter is removed from is_call_tir. I left some Todo items there for future sinfo_args matching support.
