Deduplicate when install or uninstall python (#4841)

Browse source 
When specifying the same argument multiple times, the same version will
be downloaded multiple times:

```sh

$ cargo run -- python install --preview --force 3.12.3 cpython-3.12 3.12.3 3.12
Looking for installation Python 3.12.3 (any-3.12.3-any-any-any)
Looking for installation cpython-3.12-any-any-any (cpython-3.12-any-any-any)
Looking for installation Python 3.12.3 (any-3.12.3-any-any-any)
Looking for installation Python 3.12 (any-3.12-any-any-any)

This PR deduplicates the `ManagedPythonDownload` before `install` or
`uninstall`:

```sh
$ cargo run -q -- python install --preview --force 3.12.3 cpython-3.12 3.12.3 3.12
