`uv run --with=X` shouldn't install `X` if it's already available #4547

If it's already part of the project (and thus the environment), we shouldn't need to install it. Same goes for any of the dependencies of X.

This requires that we have some concept of "packages that are available, but not in our current environment". It causes some problems for the install plan. In some ways it's conceptually similar to respecting multiple sys.path entries.

I can be responsible for this though unclear on its priority.
