cockroach sql,sqlstats: lift out fields required for logging from `dispatchToExecutionEngine`

sql: record topLevelQueryStats in instrumentationhelper

Previously topLevelQueryStats were being passed directly into the logging function after execution in dispatchToExecutionEngine. This commit persists the top level stats of the query execution into the planner's instrumentation helper, similar to what we do with sampled query exec stats. This allows us to move the logging operation in dispatchToExecutionEngine to execStmtInOpenState.

sql, sqlstats: construct statement fingerprint id on demand when logging

Currently we construct the stmt fingerprint id at various places to pass to the logging function. We only need the statement fingerprint id for telemetry logging, so this construction is wasteful in other scenarios. This commit moves the stmt fingerprint id generation to the logging function.

Summary:

Record the current stmt fingerprint id in the stats collector when writing sql stats. This value is reset at the start of stmt exec.
Construct stmt fingerprint at the time of logging based on the AST in the planner if it was not available in the stats collector.

This change is motivated by the desire to move logging from disatpchToExecutionEngine to execStmtInOpenState. See issue for details.
