Damien Neil 0ae1c9789a internal/impl: lazy extension decoding
Historically, extensions have been placed in the unknown fields section
of the unmarshaled message and decoded lazily on demand. The current
unmarshal implementation decodes extensions eagerly at unmarshal time,
permitting errors to be immediately reported and correctly detecting
unset required fields in extension values.

Add support for validated lazy extension decoding, where the extension
value is fully validated at initial unmarshal time but the fully
unmarshaled message is only created lazily.

Make this behavior conditional on the protolegacy flag for now.
