Reorganize server observability packages

Browse Source 
Prior to this commit, the server observability support would create a
cycle in Java packages.

This commit refactors the current arrangement to solve this by:

* "flattening" the reactive HTTP instrumentation; this removes the
  dependency to the `ServerWebExchange` and `PathPattern` types
* moving the `observation` package under
  `org.springframework.http.server` and
  `org.springframework.http.server.reactive`

See gh-29477
