This commit reorganizes the asciidoctor attributes for the reference
documentation. Instead of being contributed partially by the build and
individual documents, attributes are now shared in common files that are
included in top sections.
Includes corresponding build upgrade to Tomcat 10.1.1 and Undertow 2.3.0
(while retaining runtime compatibility with Tomcat 10.0 and Undertow 2.2)
Closes gh-29435

This commit configures the documentation build to merge the entire
reference documentation into a single PDF file.
To achieve that, this commit also fixes duplicate anchors that were
introduced while factoring out common parts of the documentation for MVC
and WebFlux.
Closes gh-28451
This commit creates a new "framework-docs" module, which is dedicated to
documentation generation (reference and API docs).
This commit refactors the build configuration and moves the asciidoc
files to a separate location, but does not change the name nor the
nature of published artifacts.
