chore(ec2): support new vpc flow log fields in v7 (aws#30202)

### Reason for this change

VPC Flow log added several fields regarding ECS in v7.
https://aws.amazon.com/about-aws/whats-new/2024/05/amazon-vpc-flow-logs-extends-support-ecs/
https://docs.aws.amazon.com/vpc/latest/userguide/flow-logs.html#flow-log-records

This change supports these fields in L2 construct.

### Description of changes

Added new log fields to `LogFormat` class.

### Description of how you validated changes

Unit test and integ test are both updated. Changes of logFormat configuration requires resource replacement, which is necessary.
It seems like that in order to enable these ecs related log fields, at least one ECS cluster is required in the VPC. So a new ECS cluster is also created in the integ test.
