Add type hints.

Description of Changes

Some type hint updates during custom component work.
I am assuming Python 2 is still supported, so I'm limiting these to docstrings/comments and not using type annotations.

Testing Done

Able to build/rebuild EPIC Mannequin template in 5.1.2 and 5.2.1.

decided not to use type hints for consistency

[timothyliu3d]

@miquelcampos in case this is a misunderstanding, I feel I should clarify that these changes are all limited within the docstrings, and are not the inline type annotations.

The goal is to provide real data types for auto-complete or agents.
E.g. current use of "pyNode" (or "dagNode") is generally understood, but "pm.node._Node" refers to a real class that IDEs can recognize to help with the authoring process.

🟢 What this is trying to do:

def func(param1):
    """Description

    Arguments:
        param1 (str): description.

    Returns:
        pm.node._Node: Still within the docstring, but using the actual class instead of "pyNode" or "dagNode".
    """
    pass

❌ What this is NOT:

def func(param1: str) -> bool:
    """Description"""
    pass
