lib: move handling of data->req.writer_stack into Curl_client_write()

- move definitions from content_encoding.h to sendf.h
- move create/cleanup/add code into sendf.c
- installed content_encoding writers will always be called
  on Curl_client_write(CLIENTWRITE_BODY)
- Curl_client_cleanup() frees writers and tempbuffers from
  paused transfers, irregardless of protocol

Closes #11908
