Allow specification of additional requirements in uv tool run (#3678)

Allows requesting additional transitive dependencies when running a
tool.

e.g. `uv tool run -v --with anyio ruff check example.py` (Why would you
want anyio with ruff? Who knows 😄)

The motivation for doing this now is that I think the first
implementation of `uv tool install` might just shim into `uv tool run`
with pinned dependencies? Regardless this is something we need in the
long run and is a trivial addition right now.
