feat(events-targets): support Amazon Data Firehose target using Firehose's IDeliveryStream (#33798)

### Issue # (if applicable)

Related to #33757 and #33758

### Reason for this change

The module has the `KinesisFirehoseStreamV2` target class for Firehose delivery stream.
But it has following issues:
- Kinesis Data Firehose is now Amazon Data Firehose. Therefore the class should not be called Kinesis. Also, KinesisFirehoseStream is confusable with Kinesis Data Stream.
- The constructor receives internally defined `IDeliveryStream` which is a subset of `aws_kinesisfirehose.IDeliveryStream` without inheritance. This may cause jsii type compatibility problem.

### Description of changes

- Added a new `FirehoseDeliveryStream` target class derived from `KinesisFirehoseStreamV2` but receives `aws_kinesisfirehose.IDeliveryStream` instead.
- Deprecated `KinesisFirehoseStreamV2` and internal `IDeliveryStream`.
- Added missing unit tests for `FirehoseDeliveryStream`
- Updated the integ test to use `FirehoseDeliveryStream` and assertions.
- Added an missing README entry refers Amazon Data Firehose.

### Describe any new or updated permissions being added

N/A - `FirehoseDeliveryStream` adds same permissions as `KinesisFirehoseStreamV2`

### Description of how you validated changes

Unit tests and integ test.
