Change `spring-boot-tomcat-runtime` and `spring-boot-jetty-runtime`
into starter POMs and reduce the number of dependencies needed for
`spring-boot-tomcat` and `spring-boot-jetty`.
The runtime starters provide only the jars required to run the
embedded server along with the module jar itself (excluding transitive
dependencies) and `spring-boot-webserver` (excluding transitive
dependencies).
The build setup required for an executable jar is slightly different
between Maven and Gradle. For Maven, the regular module is put in the
`provided` scope. For Gradle, the regular module remains in main
configuration and the runtime jar is put in the `providedRuntime`
configuration. The reference documentation has been updated to
show how to configure things if starters are being used.
Manual testing has been performed to ensure that wars build with Maven
and Gradle work with both Tomcat and Jetty in both deployed and
`java -jar` modes.

Prior to this commit, our Jetty support for compression was using the
`GzipHandler` which is deprecated as of Jetty 12.1.
This commit adds two new dependencies to the module and uses the new
`CompressionHandler` with the `GzipCompression` algorithm.
Closes gh-47134
Refactor `PropertyMapper` so that it no longer calls adapter or
predicate methods by default when the source value is `null`. This
effectively makes all default calls the same as using
`alwaysWhenNotNull` in the previous generation of the code.
For the limited times when you do need to deal with `null` values, the
new `always()` method can be used.
For example,
map.from(source::method).to(destination::method);
Will not call `destination.method(...)` if `source.method()` returns
`null`.
Where as:
map.from(source::method).always().to(destination::method);
Will call `destination.method(null)` if `source.method()` returns
`null`.
This update provides clearer semantics for the API and allows for better
JSpecify nullability annotations. It has also simplified much of our
existing property mapper code.

Spring Framework 7.0 requires a Servlet 6.1 baseline for Servlet containers.
Partial Servlet 6.1 support is available on the `main` Undertow branch,
but there isn't any milestone version available for the undertow 2.4
generation. At this stage of our 4.0 schedule, we think it's safer to drop
Undertow support now.
Closes: gh-46917
The enum itself is not specifically tied to auto-configuration so
spring-boot is a better place for it. The related condition,
`@ConditionalOnThreading`, remains in spring-boot-autoconfigure. This
aligns things with the similar `CloudPlatform` and
`@ConditionalOnCloudPlatform`.
Closes gh-46406
