Clang: Add tooltip action to copy to clipboard

...as selecting text in the tooltip was difficult and eventually got
disabled due to other problems - see
d58c0a9ac8123fd81c335b322defbbb567de840d.

This adds support for actions in TextMarks. They are displayed as
QToolButtons in a dedicated column in the tooltip.
