Quote ETag if not quoted in HttpHeaders#setETag

Browse Source 
This aligns HttpHeaders with other places like ServletWebRequest and
DefaultWebExchange where an ETag is accepted as input.

It also allows us to remove quoting from places that delegate to
HttpHeaders#setETag since it now does that internally.

Closes gh-33412
