bpo-133311: have MIMEImage respect policy.max_line_length 
This patch updates Lib/email/mime/image.py so that MIMEImage honors the max_line_length
setting from the provided EmailPolicy when Base64-encoding image payloads.

- Adds imports for base64 and textwrap.wrap
- Replaces the old `self.set_payload(_imagedata)` + `_encoder(self)` calls
  with an explicit Base64 encode, wrap to `policy.max_line_length` (default 76),
  and then calls `self.set_payload` with the wrapped text.
- Ensures CRLF line endings and proper headers are still applied by set_payload.
