Seeding venv adds setuptools and wheel on Python 3.12

[henryiii]

If you use --seed on a Python 3.12 venv, you still get setuptools and wheel, while both virutalenv and venv have dropped them if using Python 3.12 or newer. This causes uv venv -p 3.12 --seed (524ms) to be slower than virtualenv .venv (360ms), which is only adding pip.

Thanks! We can drop them too.
