Exception hierarchy under WebClientResponseException for the WebClient [SPR-17145]

[spring-projects-issues]

Rossen Stoyanchev opened SPR-17145 and commented

Same idea as for #19967 but for the WebClient.

The WebClient does have the onStatus transformer methods to customize the exceptions, but there is no need for everyone to re-create the same.
