Fix Appx in PSRemoting for Server 2025

Appx-Server2025.ps1

# Server 2025 fails to run Get-AppxPackage and other DISM module commands in
# a PSRemoting (psrp) session as it has a dependency on some dll's not present
# in the GAC and only in the powershell.exe directory. As PSRP runs through
# wsmprovhost.exe, it fails to find those dlls. This hack will manually load
# the 4 required dlls into the GAC. This is a hack and should be removed in the
# future if MS fix their bug on 2025.
