Deactivate mypy for _functional_pil.py and video_reader.py

[NicolasHug]

Towards #8377

This PR deactivates mypy for _functional_pil.py because it started failing with PIL 10.3 with absurd errors like:

  torchvision/transforms/_functional_pil.py:242: error: Module has no attribute
  "BILINEAR"  [attr-defined]
          interpolation: int = Image.BILINEAR,

  "PERSPECTIVE"  [attr-defined]
          return img.transform(img.size, Image.PERSPECTIVE, perspective_coef...

which is not true, PIL.Image does have those attributes, they're just set dynamically at import time (thanks @pmeier for pointing that out!) https://github.com/python-pillow/Pillow/blob/58a47978af9f34851ce926303d05fa677010ce2a/src/PIL/Image.py#L203-L206

This also deactivates mypy for video_reader which is failing with

              av = ImportError(

That module will be deprecated soon, so there's no point spending time on it.

LGTM. Static type checks on dynamically set attributes will always be a problem 😕
