[FLINK-36027][cdc-connector][mysql] numRecordsOut/numRecordsOutRate metrics for each OperationType

[SML0127]

Added numRecordsOut/numRecordsOutRate metrics for each OperationType INSERT, UPDATE, DELETE.

Removed table identifier from metrics name. With monitoring tools such as prometheus, we can distinguish flink job, db, and table using metric attributes.

Don't support this metrics for snapshot phase. Because, the value will be same with numRecodsOut, numRecordsOutRate in Flink.
