Changes introduced on main server selection path to accommodate negatively affect performance in a number of performance tests. Links to evergreen notifications listed in dev comment

Acceptance Criteria 

• Inspect all server selection events to see if any costly operations (duplicate function calls, deep clones etc)
• Feature flag topology.ts every time it creates a server selection event, so that the event object is only created when logging is turned on for that component and severity level

Testing Requirements

• Rerun Affected Tests, and record new % change

• • findOne - 6% throughput reduction
  • runCommand - 9% throughput reduction
  • smallDocInsertOne - 6.5% throughput reduction
• Ensure that when mongologger is turned off for server selection, we do not create server selection events
