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.

This commit refines the JSP view resolver documentation contribution
by using tabs for Java and XML configuration, with Java displayed by
default.
Closes gh-35444
Since we now use asciidoctor-tabs instead of spring-asciidoctor-backends,
we no longer need the `role="primary"` and `role="secondary"` attributes
for tab groups.
Closes gh-33506
This commit extract spring-related links and recurring external links
into asciidoctor attributes to be used by the Antora toolchain.
It notably homogenizes links to:
- IETF RFCs
- Java Community Process JSRs
- the Java API Documentation (on the Java 17 version)
- Kotlin documentations (on the Kotlinlang.org version)
- the Spring Boot reference guide (on the `html` version)
This commit also reworks most link attributes to follow a
Project-Category-Misc syntax. For example, `spring-boot-docs` rather
than `docs-spring-boot`.
Finally, it makes an effort to clean up remainders from the previous
documentation toolchain, namely the `docs/asciidoc` folder and
`modules/ROOT/pages/attributes.adoc` file.
