Charles Dang 7188781f91 GUI2: made link_aware a per-instance config option rather than per-definition
Back when link awareness was first added (https://github.com/wesnoth/wesnoth/pull/300), this key was added
globally to label definitions alongside link_color. This had the unintended side effect of making *all* labels
link aware, leading to issues such as being able to open a do-you-want-to-open prompt from an instance of the
same ad-infinitum.

This became an active issue after 213453e6cf78371360471ac4d110602aafecd9f3, since now that labels could capture
focus if link_aware was true - which it always was for most labels - labels in toggle panels would always
grab mouse_motion events and no longer allow their parent toggle panels to gain their hovered states. That
appears to be in keeping with the design of GUI2, and a further evaluation of that issue is needed at a later
time. However, the fact remains that almost every single label was marked as link-aware, even when in almost every
case that was not the desired behavior.

This change move the link_aware config option to individual label and scroll_label instances. The following uses
had this explicitly enabled:

- Addon license prompt
- Addon descriptions
- Campaign descriptions
- The Server Info popup
- The chatbox
