ExtensionManager: Implement latest plugin status UI specification

The switch to enable or disable the selected plugin moves from the lower
right corner to the top right of the middle column.

The "Restart Now" button is replaced by an InfoBar entry.

The "Loaded"/"Installed" on the extension cards change to
"Active"/"Inactive".

Fixes: QTCREATORBUG-31856
