Fix include_http_headers on Spring Boot 3.x/Jakarta, unify Tomcat/Jetty servlet plugins (#13938) (#812)

* Fix include_http_headers on Spring Boot 3.x/Jakarta, unify Tomcat/Jetty servlet plugins (#13938)

Add a shared servlet-commons module: a JDK-typed, namespace-agnostic servlet
request/response wrapper that resolves javax.servlet vs jakarta.servlet at
runtime through a single dispatch point. Refactor the Spring MVC commons onto
it, removing the fragile static javax/jakarta detection that silently dropped
plugin.http.include_http_headers on Jakarta (Spring Boot 3.x) applications.

Merge the duplicated servlet plugin pairs, each now covering both namespaces:
- tomcat-7.x-8.x + tomcat-10x  -> tomcat
- jetty-server-9.x + jetty-server-11.x -> jetty-server
Breaking change: the plugin definition names change accordingly; update any
plugin.exclude_plugins (SW_EXCLUDE_PLUGINS) settings referencing the old names.

Add E2E scenarios spring-boot-3.x (Boot 3 embedded Tomcat 10, jakarta) and
spring-boot-2.x (Boot 2, javax mirror), both asserting http.headers and
http.params; port the tomcat/jetty interceptor unit tests to the merged
modules; bump jakarta framework versions (one per minor); update docs.

* Add servlet-commons provided dependency to mvc-annotation-4.x-plugin

Its interceptor unit tests exercise the commons AbstractMethodInterceptor, which
now references servlet-commons' HttpRequestWrappers. Since commons declares
servlet-commons at provided (non-transitive) scope, it was absent from the 4.x
plugin's test classpath, causing NoClassDefFoundError in CI.

 9.7.0
 ------------------
 
+* Fix `plugin.http.include_http_headers` not working on Spring Boot 3.x / Jakarta EE (apache/skywalking#13938).
+* Unify the Tomcat plugins into a single `tomcat` plugin (Tomcat 7 - 10) and the Jetty server plugins into a single `jetty-server` plugin (Jetty 9 - 11), each supporting both `javax.servlet` and `jakarta.servlet`. Breaking change: plugin names `tomcat-7.x/8.x` and `tomcat-10.x` are replaced by `tomcat`, and `jetty-server-9.x` and `jetty-server-11.x` by `jetty-server`; update `plugin.exclude_plugins` if you reference the old names.
 * Added support for Lettuce reactive Redis commands.
 * Add Spring AI 1.x plugin and GenAI layer.
 * Fix httpclient-5.x plugin injecting sw8 propagation headers into ClickHouse HTTP requests (port 8123), causing HTTP 400. Add `PROPAGATION_EXCLUDE_PORTS` config to skip tracing (including header injection) for specified ports in the classic client interceptor.
