GEODE-10294: Compare invalid token during putIfAbsent retry. (#7738)
* During putIfAbsent retry, comparing invalid token value when
putIfAbsent of a null value.
* Do not make putIfAbsent event to update event if current
entry value is null or invalidate and is a retried event.
> Need to consider invalid token when comparing value during putIfAbsent

> Key: GEODE-10294
> URL: https://issues.apache.org/jira/browse/GEODE-10294
> Project: Geode
> Issue Type: Bug
> Components: regions
> Affects Versions: 1.15.0, 1.16.0
> Reporter: Eric Shu
> Assignee: Eric Shu
> Priority: Major
> Labels: blocks-1.15.0, pull-request-available
>
> During retry of putIfAbsent, there is a possibility that value has been
> created by the initial operation. Geode treats this as a successful
> operation, so that client initiated the operation will also create the entry
> in its local cache. However, putIfAbsent of null is a special case, as an
> Invalid Token is created instead of null value being put into the region
> entry. Need to handle this special case for above value comparison.
