[free threading] Support for free threading Python in torchvision

[atalman]

The nightly builds for Python 3.13t are now enabled in Linux, Linux aarch64, MacOS and Windows:
https://hud.pytorch.org/hud/pytorch/vision/nightly/1?per_page=50&name_filter=3_13t

We would like to:

1. audit trochvision code for thread safety
2. perform parallel testing and identify failures
3. Work on fixing these failures
