Bug 1533293 - part 2: Rewrite EditorBase::SelectEntireDocument() and its overrides r=m_kato
`EditorBase::SelectEntierDocument()` uses `Selection::Extend()` but it's too slow. It should use `Selection::SetStartAndEndInLimiter()` instead. Additionally, `TextEditor::SelectEntierDocument()` shrink the result of `EditorBase::SelectEntierDocument()` with `Selection::Extend()` if there is a `moz-<br>` element. So, `TextEditor::SelectEntinerDocument()` should set its expected selection with a call for saving the runtime cost. Then, we don't need to make `EditorBase::SelectEntierDocument()` as non-pure virtual method. So, this patch makes each its callers call `Selection->SelectAllChildren()` directly.
