Add `--override` to `uninstall`

[Rotzbua]

Description of the new feature / enhancement

Current only install provides an option to pass a string directly to the installer. It would be useful to have this option also for the uninstall process.

Use cases:

• installation was done with override and now required for the uninstallation
• buggy uninstaller which required special input
• simple workaround for more difficult implementations like Manifest fields for custom uninstall arguments and return codes #1885#
• manually provide silent flag for uninstallers which do not set a silentuninstall registry entry Nullsoft installer installed application don't uninstall silently #1368

Proposed technical implementation details

Same as install.

+1 There are some vendors that have specific switches needed to uninstall their application gracefully and silently.

I found a major offender is the Visual Studio Installer.

You can install it silently via winget:

$opt = (
    "--wait",
    "--quiet",
    "--add Microsoft.VisualStudio.Workload.NativeDesktop",
    "--includeRecommended"
)

winget install vs18-community --override "$opt"

But you can't uninstall it.
