text: Title: Global disable_web_page_preview parameter
  Body: **Is your feature request related to a problem? Please describe.**
  Set `disable_web_page_preview` in `aiogram.Bot`:
  `bot = aiogram.Bot(token=..., disable_web_page_preview=...)`
  
  **Describe the solution you'd like**
  Like logic with `parse_mode`, but with `disable_web_page_preview` (https://github.com/aiogram/aiogram/blob/358ecc78213183adeb70809d7f3e95f1524657fb/aiogram/bot/bot.py#L311-L312):
  ```
  if self.disable_web_page_preview and entities is None:
      payload.setdefault('disable_web_page_preview', self.disable_web_page_preview)
  ```
     
  In ideal, need paste that piece of code to all methods with messages where supports `disable_web_page_preview`
