REGTESTS: quic: test H3 request without content-length

Add a QUIC regression test for an HTTP/3 request body without
Content-Length forwarded to an HTTP/1 backend.

The client side sends a chunked HTTP/1 request to a first HAProxy
instance, which forwards it to a second HAProxy instance over QUIC/H3.
The second instance then forwards it to a plain HTTP/1 server. This
exercises the H3 frontend to H1 backend path with an unknown request
body length.
