Winget-cli: Support for installation of fonts

[sob]

Description of the new feature/enhancement

As part of a new system build, I typically install a handful of fonts including Cascadia Code and other powerline enabled fonts. These fonts don't have an installer associated with them but instead need to be manually downloaded, extracted, and installed.

Alternately, maybe just installing a font manager like SkyFonts would work just as well without adding specific font-related features to winget.

(Hiding this because I meant it as a helpful note for people who wanted an immediate solution, but it's otherwise not relevant to this particular feature request.)

Be sure to enable installing a font as a non-admin user!

Installing a CLI font manager might be acceptable.

Installing a _CLI_ font manager might be acceptable.

Not my preference. There should maybe be a special flag for fonts, but not another font manager.

Neither are needed. All that's needed is for the font to be uninstalled first, then the updated version is installed after. Some apps or stuff in Windows will need a font-fallback during this process if they're configured to use that font. So winget just needs to support the unattended uninstallation and installation of the font.
