Add class helper ChatAction

[ShiroNoHaga]

Description

Add class helper ChatAction for constants that Telegram BotAPI uses in send_chat_action request.
In my opinion, this will help users and will also improve compatibility with 2.x version.

Difference from 2.x version:
• No class methods;
• Renamed ChatActions to ChatAction;
• Better class description.

Updated. Change using helper to using enum.Enum.

Small test code:

from aiogram.types.chat_action import ChatAction
from aiogram import types
import aiogram


async def main():
    assert types.ChatAction == ChatAction
    assert aiogram.types.ChatAction == ChatAction
    assert aiogram.types.ChatAction.TYPING == ChatAction.TYPING
    assert ChatAction.TYPING == "typing"
    print("Import tests passed.")

    from aiogram import Bot
    BOT_TOKEN = ""  # bot token here
    CHAT_ID = 0     # user id to send action

    bot = Bot(BOT_TOKEN)
    await bot.send_chat_action(chat_id=CHAT_ID, action=ChatAction.TYPING)
    await bot.send_chat_action(chat_id=CHAT_ID, action="typing")
    await bot.session.close()
    print("Implementation tests passed.")


if __name__ == '__main__':
    import asyncio
    loop = asyncio.get_event_loop()
    loop.run_until_complete(main())

@evgfilim1, don't forget to add it to 2x->3x migration guide

enum.auto() is not typehinted, so MyPy can't recognise auto()'s result as str
