lib: send rework
Curl_read/Curl_write clarifications

- replace `Curl_read()`, `Curl_write()` and `Curl_nwrite()` to 1clarify
  when and at what level they operate

- send/recv of transfer related data is now done via
  `Curl_xfer_send()/Curl_xfer_recv()` which no longer has
  socket/socketindex as parameter. It decides on the transfer setup of
  `conn->sockfd` and `conn->writesockfd` on which connection filter
  chain to operate.

- send/recv on a specific connection filter chain is done via
  `Curl_conn_send()/Curl_conn_recv()` which get the socket index as
  parameter.

- rename `Curl_setup_transfer()` to `Curl_xfer_setup()` for naming
  consistency

- clarify that the special CURLE_AGAIN handling to return `CURLE_OK`
  with length 0 only applies to `Curl_xfer_send()` and CURLE_AGAIN is
  returned by all other send() variants.

SingleRequest reshuffling

- move functions into request.[ch]
- differentiate between reset and free
- add Curl_req_done() to perform last actions
- add a send `bufq` to SingleRequest for future use in keeping upload data

Closes #12963
