Add API in texteditor to let plugins contribute extra selections.

Browse Source 
Some plugins use extra selections to provide additional editor annotations: code coverage, spelling
mistake... This was possible for C++ editor in previous version, using
CppModelManagerInterface::setExtraDiagnostics(), but this API has been removed.

This commits adds alternative API directly in the editor, allowing to pass a Core::Id instead of
the enum value.
