[FLINK-8421] [test] Increase MAX_MEM_STATE_SIZE and Akka framesize in…

… AbstractEventTimeWindowCheckpointingITCase

After adding the TypeSerializerConfigSnapshots of timer serializers to
the timers snapshots, the size of the timer snapshots have potentially
doubled. This caused the AbstractEventTimeWindowCheckpointingITCase to
be failing, because the configured max memory state size and Akka
framesize were too small. This commit doubles those sizes.

This closes apache#5362.
