b13b10a8 - Extend collate function that can register collate functions to handle specific types (#85748)

Extend collate function that can register collate functions to handle specific types (#85748) As per request from Vision team, adding `collate` function with an extra argument of `collate_fn_map` to dispatch custom collate functions for non-collection objects and specific objects. If the type of batch element is not present in`collate_fn_map`, it will go through all keys in the insertion order to check if the type is a subclass of the key. If so, it will invoke the corresponding collate functions. And, `default_collate` will utilize the `collate` function with a few by default collate function for `int`, `float`, `str` and `numpy object`. Benefit: - Domain teams can register their own `collate` function to handle their specific type of objects - Easier for users to extend from the `collate` function.
