Hide deprecated chromium from tool listings when not installed

After #14334 deprecated the chromium installer, `quarto list tools` and
`quarto check install` still show chromium as "Not installed" even for
users who never had it. This is noise — no one should be installing it.

Add `isDeprecatedTool()` helper to filter deprecated tools from both
`loadTools()` and `allTools()` when not installed. Users with chromium
still installed see it (with the deprecation hint) so they can uninstall.
The helper and chromium registry entry get removed entirely in v1.11.

Also adds a CI assertion in test-install.yml to verify chromium does not
appear in `quarto list tools` after the redirect install.
