Capsule class abstract

Base class for the Capsule Protocol (RFC 9297).

Each capsule on the wire is: VarInt(Type) + VarInt(Length) + Data (Length bytes)

NOTE: This HTTP/3 Capsule class is distinct from the Capsule class in lib/src/webtransport/capsule_types.dart. Both are exported from quic_lib.dart (via different barrel files), which creates a naming ambiguity when both are imported. This will be resolved in v2.0.0 by renaming the WebTransport class to WebTransportCapsule.
