Record header compression ratio.

Record compression ratio for all headers sent and received via QUIC, separately
for HPACK and QPACK compressed ones, so that they can be compared.  Compressed
size excludes stream frame overhead in all cases.

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