[roll] Roll fuchsia [roll] Roll third_party/pigweed pw_bluetooth_sapphire: Cache serialized SDP payloads

Cache the fully serialized response payload inside sdp::Server on
a per-channel basis. When continuation requests arrive, the server looks
up the cached payload and slices directly from it rather than running
the database search query, re-cloning attributes, and re-serializing the
entire attribute tree. This prevents an asymmetric heap/CPU
amplification DoS (from ~1500x amplification down to ~19x).
