pw_protobuf: Add StreamEncoder::CloseEncoder

Previously, `StreamEncoder` would only perform writes to its parent
after destruction occurred. This resulted in callers frequently needing
to introduce new scopes, often with a comment explaining the API to
readers.

This change adds the `CloseEncoder` method, which explicitly finalizes
the child encoder and performs the writes to the parent, allowing users
both to close an encoder before the end of its lexical scope and to make
their code more explicit and self-descriptive if desired.
