Add ability to list installed packages by `--installer-type` with `winget list`

[o-l-a-v]

Description of the new feature / enhancement

Just now I wondered what portable packages I've installed with Winget, and found that winget list doesn't really have such filtering capabilities.

Here's the current options with winget list:

• https://learn.microsoft.com/en-us/windows/package-manager/winget/list
• https://github.com/microsoft/winget-cli/blob/master/doc/windows/package-manager/winget/list.md

Here's the supported installer types:

• https://learn.microsoft.com/en-us/windows/package-manager/winget/#supported-installer-formats

Here's an example portable package:

• https://github.com/microsoft/winget-pkgs/blob/master/manifests/g/Gyan/FFmpeg/6.1/Gyan.FFmpeg.installer.yaml

Proposed technical implementation details

Add option to specify --installer-type with winget list.

Here's a powershell script which takes a stab this, with a bunch of help from github copilot:
