[stdlib] Updated the doc comments for `PlaygroundQuickLook`/`CustomPlaygroundQuickLookable`.

Since these are now deprecated (in preparation for removal in a future Swift
release), the doc comments reflect that and provide suggestions for what to do
instead (i.e. use `CustomPlaygroundDisplayConvertible`) and how to
conditionalize usage of `PlaygroundQuickLook`/`CustomPlaygroundQuickLookable` so
that source code remains compilable both by old versions which only have the old
protocol and newer versions which have removed the old protocol.
