Register extension with PowerToy Run

[kzu]

PowerToy Run is awesome and it's extensible.

We just need to copy a plugin to the %LocalAppData%\Microsoft\PowerToys\PowerToys Run\Plugins folder.

The experience should involve typing vs[space] > [list vs versions ]. If you specify valid VS arguments (like vs ent +web for example, the plugin should run the vs where command with those switches and filter the list of VSes shown to those matching the criteria.

See C:\Program Files\PowerToys\modules\launcher to inspect how it's run, https://github.com/microsoft/PowerToys/tree/master/src/modules/launcher for the source of the built-in plugins.
