lib: drop, or replace sendf.h with curl_trc.h where possible
- replace `sendf.h` with `curl_trc.h` where it was included just for it.
- drop unused `curl_trc.h` includes.
- easy: delete obsolete comment about `send.h` include reason.

Also:
- move out `curl_trc.h` include from `sendf.h` and include it directly
  in users, where not done already. To flatten the include tree and
  to less rely on indirect includes.
- stop including `sendf.h` from other headers, replace it with forward
  declaration of `Curl_easy`, as done already elsewhere.

Verified with an all non-unity CI run.

9f4f61ddcb lib: add const to clientwriter tables
Unlike the connection filter tables that hold a writable log level, the
client writer tables can be const.

client writer: handle pause before deocding
Adds a "cw-pause" client writer in the PROTOCOL phase that buffers
output when the client paused the transfer. This prevents content
decoding from blowing the buffer in the "cw-out" writer.

Added test_02_35 that downloads 2 100MB gzip bombs in parallel and
pauses after 1MB of decoded 0's.

This is a solution to issue #16280, with some limitations:
- cw-out still needs buffering of its own, since it can be paused
  "in the middle" of a write that started with some KB of gzipped
  zeros and exploded into several MB of calls to cw-out.
- cw-pause will then start buffering on its own *after* the write
  that caused the pause. cw-pause has no buffer limits, but the
  data it buffers is still content-encoded.
  Protocols like http/1.1 stop receiving, h2/h3 have window sizes,
  so the cw-pause buffer should not grow out of control, at least
  for these protocols.
- the current limit on cw-out's buffer is ~75MB (for whatever
  historical reason). A potential content-encoding that blows 16KB
  (the common h2 chunk size) into > 75MB would still blow the buffer,
  making the transfer fail. A gzip of 0's makes 16KB into ~16MB, so
  that still works.

A better solution would be to allow CURLE_AGAIN handling in the client
writer chain and make all content encoders handle that. This would stop
explosion of encoding on a pause right away. But this is a large change
of the deocoder operations.
