feat(wm): add cmds for titlebar removal

This commit introduces some basic commands to read from/add to a
whitelist of applications which that user has determined that are safe
to remove the titlebar from.

Titlebars and removed and added by removing and adding the WS_CAPTION
and WS_THICKFRAME styles (this is the approach that Workspacer also
takes) from the windows.

Wherever possible, the user should prefer native preferences and
settings that remove the titlebar in popular apps (Windows Terminal,
Firefox etc).
