fix(kinesisanalytics): deprecate using KinesisAnalyticsV2 from aws-kinesisanalytics, use aws-kinesisanalyticsv2 instead (#35519)

### Reason for this change

Sometimes services introduces a `V2` version of their APIs and CloudFormation resources.
In the past we had thought it's a good idea if `KinesisAnalyticsV2` constructs would just be included in the original `aws-kinesisanalytics` module. However since then we have come to a different view and think it's better to strictly follow what the services are doing. As of today `KinesisAnalyticsV2` is the only service that got this treatment.

We now want to clearly indicate that this is not supported and deprecate the usage from within the "V1" module.

### Description of changes

Update the `spec2cdk` package to allow services being deprecated.
I've also changed the suffix handling to be explicit instead of computed when reading from a service map. Given that we only have that one module with multiple services, this seems prudent.

### Describe any new or updated permissions being added

n/a

### Description of how you validated changes

All existing tests pass. `jsii-diff` reports no issues. Test case added for codegen of deprecated service.
