Brian Clozel b9fb384f8d Update Forwarded headers support for Framework ...

Prior to this commit, Spring Boot would auto-configure the
`ForwardedHeaderFilter`/`ForwardedHeaderTransformer` when the "NATIVE"
strategy is chosen.
Spring Framework now requires an explicit choice between the supported
HTTP header variants as of spring-projects/spring-framework#37072.

This commit adapts to this new behavior with the following:
* the "FRAMEWORK" strategy now only applies to Spring MVC and Spring
  WebFlux applications, since "NATIVE" strategies are now a good choice
  for most deployments.
* the format of HTTP headers is now configured with
  `spring.mvc.forwarded-headers.header-format` and
  `spring.webflux.forwarded-headers.header-format`, with additional
  options.

The default header format is now "X-Forwarded-*" for both NATIVE and
FRAMEWORK strategies. The reference documentation also reflects those
changes.
