Feature request: publication to official Windows Package Manager (winget) repository

[s-oldman]

Looks like the original Mupen64 is available, but not mupen64plus:

Should just be a CI/CD function; when new versions get released, a valid manifest YAML containing the new version number, hash, and URL (plus the rest of the app info, which is static) should be created and submitted via PR to the Winget repo.

Docs:

• Creating the manifest.
• Submitting to the repo. (note the folder structure)
• Client-side validation is via winget validate, Microsoft also has its own validation. The gist is that (a) the manifest file and folder structure needs to be valid, (b) the URL has to work, (c) it has to install successfully onto MS's test environments, (d) it has to pass through several antivirus scanners (not just Windows Defender), and (e) the initial submission has to be manually approved by a moderator as following community guidelines.
• GitHub Actions doesn't officially support winget, since it's not GA for Server 2019, so a different CI/CD needs to be used.
