caoxuewen bfc5569a53 [SPARK-26289][CORE] cleanup enablePerfMetrics parameter from BytesToBytesMap ... ## What changes were proposed in this pull request? `enablePerfMetrics `was originally designed in `BytesToBytesMap `to control `getNumHashCollisions getTimeSpentResizingNs getAverageProbesPerLookup`. However, as the Spark version gradual progress. this parameter is only used for `getAverageProbesPerLookup ` and always given to true when using `BytesToBytesMap`. it is also dangerous to determine whether `getAverageProbesPerLookup `opens and throws an `IllegalStateException `exception. So this pr will be remove `enablePerfMetrics `parameter from `BytesToBytesMap`. thanks. ## How was this patch tested? the existed test cases. Closes #23244 from heary-cao/enablePerfMetrics.
