Pull request overview
This PR consolidates the COM AppID registration for wsldevicehost.dll by removing a duplicate AppID GUID that was previously used specifically for the admin VirtioFS COM class. The changes update all references from the old admin-specific AppID {7F82AD86-755B-4870-86B1-D2E68DFE8A49} to the shared wsldevicehost AppID {17696EAC-9568-4CF5-BB8C-82515AAD6C09}, as COM impersonation allows the same AppID to handle both elevated and non-elevated scenarios.
Key Changes
- Removed duplicate AppID registry configuration block from the MSI package installer
- Updated CLSID registration for WslDeviceHost_VirtioFs_Admin to reference the consolidated AppID
- Updated cleanup and test code to reference the consolidated AppID

This pull request updates the AppID GUID used for the WslDeviceHost_VirtioFs_Admin COM registration to use the same AppID as the rest of the wsldevicehost COM classes. This was originally thought to support admin / non-admin VirtioFS shares, but the same AppId is able to run at both elevation levels due to COM impersonation.
There are existing tests that verify that admin / non-admin VirtioFs shares get the right permission.
