Extract functionality from the `RegistrationBean` into a new class
designed to work with dynamic registration. Servet and Filter
registration beans now extend from `DynaimcRegistrationBean`, where as
`ServletListenerRegistrationBean` extends directly from
`RegistrationBean`.
This refactor allows the removal of `ServletListenerRegistrationBean`
deprecated methods.

Now that Spring Boot supports Freemarker for both Spring MVC and Spring
WebFlux, the dedicated starter should not pull the Web starter
transitively and let developers manually choose the web stack.
Closes gh-11246
Update endpoint code to provide cleaner separation of concerns.
Specifically, the top level endpoint package is no longer aware of
the fact that JMX and HTTP are ultimately used to expose endpoints.
Caching concerns have also been abstracted behind a general purpose
`OperationMethodInvokerAdvisor` interface.
Configuration properties have been refined to further enforce
separation. The `management.endpoint.<name>` prefix provides
configuration for a single endpoint (including enable and cache
time-to-live). These properties are now technology agnostic (they
don't include `web` or `jmx` sub properties).
The `management.endpoints.<technology>` prefix provide exposure specific
configuration. For example, `management.endpoints.web.path-mapping`
allow endpoint URLs to be changed.
Endpoint enabled/disabled logic has been simplified so that endpoints
can't be disabled per exposure technology. Instead a filter based
approach is used to allow refinement of what endpoints are exposed over
a given technology.
Fixes gh-10176
