[move]Support method to determine two generic type are equal

[element2050]

Stdlib can determine two token type are equal, it depends native method name_of .

    /// Return true if the type `TokenType1` is same with `TokenType2`
    public fun is_same_token<TokenType1: store, TokenType2: store>(): bool {
        return token_code<TokenType1>() == token_code<TokenType2>()
    }

Can support method to determine any generic type are equals ？ Likes

Generic Type1 == Generic Type2 ？

Using a Global Registry is one way to achieve this, like the NFT.

public fun is_same_type<T1,T2>():bool{
   let type_info_1 = borrow_global<TypeInfo<T1>>();
   let type_info_2 = borrow_global<TypeInfo<T2>>();
   return type_info_1 == type_info_2;
}
