Inspired by c++ function `std::vector::emplace_back()`, we can use variadic template for this issue.
e.g.
```
[['struct'], 'STRUCT<TYPES>', ['TYPES'], 'ALWAYS_NOT_NULLABLE', ['TYPES...']]
```
`...TYPES` in template_types defines a variadic template `TYPE`. Then the variadic template will be expanded to multiple normal templates based on actual input arguments at runtime in FE.
But make sure `TYPES...` is placed on the last position in all template type arguments.
BTW, the origin template function logic is not affected.
