Update BView and BStringView docs

... based on Adrien's suggestions.

* Add \warning back to BView::ResizeToPreferred(), add \remark to highlight
  methods only appropriate to use as part of a BLayout.
* Clarify BView::SetFont() method and refer to BFont docs.
* Clarify BStringView::SetText(), Text(), and Draw().
* add field descriptions for BStringView::Instantiate().

The string view's text, alignment, and view flags can be set using this
constructor.

\brief Creates a new BStringView object from an \a archive message.

view's alignment flag. This should be casted to an alignment type.
Choices are:
- \c B_ALIGN_LEFT

doesn't contain an archived BStringView.
