Subject: [PATCH] GCC: explicitely move return value of SCTHashdanceMetadata::ToValue

GCC rejects to do Return Value Optimization in
SCTHashdanceMetadata::ToValue, because the copy constructor is
deleted, and in that scenario RVO is rejected in GCC:
    ../../services/network/sct_auditing/sct_auditing_reporter.cc: In member function ‘base::Value network::SCTAuditingReporter::SCTHashdanceMetadata::ToValue() const’:
    ../../services/network/sct_auditing/sct_auditing_reporter.cc:191:10: error: use of deleted function ‘base::Value::Value(const base::Value&)’
      191 |   return value;
          |          ^~~~~
    In file included from ../../services/network/sct_auditing/sct_auditing_reporter.h:14,
                     from ../../services/network/sct_auditing/sct_auditing_reporter.cc:5:
    ../../base/values.h:254:3: note: declared here
      254 |   Value(const Value&) = delete;
          |   ^~~~~
