Tidy up some of our Velocity features

A few features were marked "always disabled" and then enabled in dev,
canary and preview. I simplified those to "always enabled" and disabled
in release instead. This required changes to Generate-FeatureStaging
to make it consider `WindowsInbox` a Release branding (which, honestly,
it always should have been.)

- Feature_DynamicSSHProfiles
- Feature_ShellCompletions
- Feature_SaveSnippet
- Feature_QuickFix

Feature_DisableWebSourceIcons was deprecated in #19143, but the XML file
never got the memo.
