LibGUI: Use set_cursor() in TextEditor::set_document()

Instead of setting m_cursor directly to reset the cursor position,
TextEditor::set_document() now uses set_cursor() which will call cursor
change callback functions, if any.

This fixes a bug in HackStudio where the cursor information text would
not update immediately after changing the active TextDocument, even
though the cursor is always visibly being reset to 0, 0.
