Yichao YangandGitHub b764338415 Add feature flag for workflowIDReuse start time validation (#6231) ...

## What changed?
<!-- Describe what has changed in this PR -->
- Add a feature flag for workflowIDReuse start time validation, default
to **_disabled_**

## Why?
<!-- Tell your future self why have you made these changes -->
- The start time validation introduces one more db read for start
workflow operation. This can be avoided by adding the start time to
workflow execution state.
- Also we should only get workflow start time when TerminateIfRunning
policy is used.

## How did you test it?
<!-- How have you verified this change? Tested locally? Added a unit
test? Checked in staging env? -->
- Existing functional test `TestStartWorkflowExecution_Terminate`

## Potential risks
<!-- Assuming the worst case, what can be broken when deploying this
change to production? -->

## Documentation
<!-- Have you made sure this change doesn't falsify anything currently
stated in `docs/`? If significant
new behavior is added, have you described that in `docs/`? -->

## Is hotfix candidate?
<!-- Is this PR a hotfix candidate or does it require a notification to
be sent to the broader community? (Yes/No) -->
- Yes
