Implicit-remoting modules, at least as used by the Windows PowerShell Compatibility feature, do not honor $ProgressPreference

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version
• Search the existing issues.
• Refer to the FAQ.
• Refer to Differences between Windows PowerShell 5.1 and PowerShell.

Steps to reproduce

The Windows PowerShell Compatibility feature auto-generates script modules that use implicit remoting, such as for the Appx module.

Several of the Appx module's cmdlets put up a progress bar, such as Add-AppxPackage.

It is currently impossible to silence their progress display via implicit remoting, even with $global:ProgressPreference = 'SilentlyContinue' (the use of a global variable is - unfortunately - required due to a fundamental problem with how script modules (don't) see a caller's preference variables - see #4568)

$global:ProgressPreference = 'SilentlyContinue'

# Note: for the progress bar shown during *creation of the script module*,
#  `$ProgressPreference = 'SilentlyContinue' *is* effective.
Import-Module Appx -UseWindowsPowerShell 3>$null

# Note: Pick any *.appx file on your system that is suitable for experimentation
$packagePath = 'C:\Program Files (x86)\Microsoft SDKs\Windows Kits\10\ExtensionSDKs\Microsoft.Midi.GmDls\10.0.22621.0\Appx\Neutral\MidiVoices.appx'

Add-AppxPackage $packagePath

[Console]::Write("`nPress a key to exit."); $null = [Console]::ReadKey()

Expected behavior

No progress bar should show.

Actual behavior

A progress bar generated by Add-AppxPackage is shown.

Note: The fact that the progress bar stays visible even though Add-AppxPackage has already terminated is a separate problem stemming from the cmdlet neglecting to hide the progress bar on termination:

It seems feasible to copy the current preference variables to the remote session, but not to keep them dynamically updated if they change after creating the session.
