Only send Header Acknowledgement from QpackDecoder if required insert count is not zero.

As prescribed by
https://quicwg.org/base-drafts/draft-ietf-quic-qpack.html#header-acknowledgement.

I have a draft dynamic table encoder CL and a draft round trip fuzzer CL
relaying encoder stream data and decoder stream data between the encoder and
decoder, and I noticed this bug when patching these two CLs together.

gfe-relnote: n/a, change to QUIC v99-only code.  Protected by existing disabled gfe2_reloadable_flag_quic_enable_version_99.
