Add blocklist/inclusion list for editor commands

Eventually there is going to be a need to ignore certain Commands or Modules when PSES Registers Commands.

Here are the ideas I have had.

• Block all Registering from outside of Profile
• Block all Registering from Blacklisted Modules.
• Only Allow Registering from Whitelisted Modules
• Only Allow Registering Whitelisted Commands

You can currently do something like the following:

# Microsoft.VSCode_profile.ps1
Import-Module Blah1
Import-Module Blah2
Import-Module Blah3
Import-Module Blah4
Import-Module Blah5

# Do All The Things Here

Unregister-EditorCommand -Name Command1FromBlah1
Unregister-EditorCommand -Name Command2FromBlah1
Unregister-EditorCommand -Name Command1FromBlah2
Unregister-EditorCommand -Name Command2FromBlah2
Unregister-EditorCommand -Name Command3FromBlah3
Unregister-EditorCommand -Name Command1FromBlah4
Unregister-EditorCommand -Name Command1FromBlah5
Unregister-EditorCommand -Name Command2FromBlah5
Unregister-EditorCommand -Name Command3FromBlah5

However, this would quickly become a headache and hard to maintain if a Module is regularly adding commands etc.

Start by reviewing how PSES registers commands and how Unregister-EditorCommand removes them, using the profile example as the expected configuration context. Compare the proposed module and command allowlists/blocklists and clarify which policy should be supported first. Done means a decided registration policy that avoids manually unregistering commands as modules change.
