This commit adds a menu item to the message context menu to
copy links that may exist inside of a message.
There are three possible scenarios:
1. There's no link in the message, which causes the menu to not
render the dedicated menu item at all
2. There's one link in the message, which renders an additional
`Action` with a copy-to-clipboard functionality
3. There are multiple links in a single message. This adds a
nested `PopupMenu` in the existing menu with menu items for each
link extracted from the message
To make this work there were some changes in the `PopupMenu` component
needed, as it wasn't take the sub menu's `enabled` state into account
properly. This makde it always render nested menus even when they
should've been invisible.
Closes: #1733
