Pin audit command

Description of the new feature / enhancement

Packages can be added, removed, and updated (or downgraded!) outside of winget. As a user, I would like to be able to check if any of my pins have been violated.

If the package has a standard ("pinning") or blocking pin and the version has changed, I'd like to be informed what the version pinned in winget was, and what the currently installed version is.

If the package has a gating pin and the installed version violates the gate, I'd like to be informed what the gate in winget is, and what the currently installed version is.

If a pin exists and no installed package can be found, I'd like to be informed what the version pinned / gate in winget was, and the current installation status is "Not found"
