'SizedBuilder' is a 'Data.ByteString.Builder' paired with its
byte length, accumulated as the builder is assembled.  Used
inside RR-data encoders when an outer length-prefixed field
needs the encoded value's length up front (RDLENGTH and the
16-bit length prefixes that introduce SVCB option values, EDNS
option values, and similar).  The @mb*@ converters wrap the
corresponding low-level builders so their byte-cost is
tracked.
