IMPALA-10995: Allow remote submit time to be in the past

This patch adds a new interface to RuntimeProfile::EventSequence that
does not DCHECK timestamps in the past like Start() does. This new
interface is used to initialize the query profile timeline for external
frontends. Also made a small change to avoid copying TExecuteStatementReq
in ImpalaServer::TExecuteStatementReqToTQueryContext.

Tested using external frontend. It is not practical to automate the
scenario that caused the DCHECK to fire.
