Deprecate "feed" and "document" view packages

Browse Source 
Prior to this commit, Spring Framework would ship several abstract
`*View` implementations for rendering PDF, RSS or XLS documents using
well-known libraries. More recently, supporting libraries evolved a lot
with new versions and forks. Spring Framework is not in a position to
efficiently support all variants within the project.

This commit deprecates the relevant classes. Instead, libraries can
reuse existing code and ship optional support for Spring directly.
Often, updating imports and library usage is enough.
As an alternative, applications can decide to perform rendering
direclty in web handlers.

Closes gh-35451

Spring offers ways to return output other than HTML, including PDF and Excel spreadsheets.
This section describes how to use those features.

== Introduction to Document Views
An HTML page is not always the best way for the user to view the model output,
and Spring makes it simple to generate a PDF document or an Excel spreadsheet
dynamically from the model data. The document is the view and is streamed from the
