Add support for concurrently reading from an HTTP/1 request body
while writing the response.
Normally, the HTTP/1 server automatically consumes any remaining
request body before starting to write a response, to avoid deadlocking
clients which attempt to write a complete request before reading the
response.
Add a ResponseController.EnableFullDuplex method which disables this
behavior.
For #15527
For #57786
