sw content controls: select the content on click when showing placeholder

- teach SwCursorShell::GetContentAtPos() about a new IsAttrAtPos::ContentControl

- add a new SwCursorShell::GotoFormatContentControl() to select a
  content control, and a SwWrtShell::GotoContentControl() wrapper around
  it

- combine these together in SwEditWin::MouseButtonUp()

The intention is that when you open a document and you click on a
placeholder text like "Click here to enter text", then this content is
pre-selected (so typing overwrites it), but typing real content there
disables this behavior.
