[FLINK-19326] Allow explicitly configuring time behaviour on CEP PatternStream

• Type: Sub-task
• Status: Closed
• Priority: Major
• Resolution: Implemented
• Fix Version/s: 1.12.0
• Component/s: Library / CEP
• Labels: pull-request-available

Release Note

Before Flink 1.12 the CEP operations were changing their behavior based on the globally set Stream TimeCharacteristic. In Flink 1.12 we introduced explicit `inProcessingTime()` and `inEventTime()` methods on `PatternStream` and the CEP operations no longer change their behaviour based on the global characteristic.

Description

With the deprecation of StreamExecutionEnvironment.setStreamTimeCharacteristic() in FLINK-19319 we need a way of explicitly configuring the time behaviour of CEP operations. Currently, all CEP operations use the characteristic to configure themselves.
