Support HostPrefix in E2.0, enable E2.0 for all services

[dagnir]

Motivation and Context

This changes fixes the previously incorrect handling of hostPrefix in services, causing requests for some services to have the wrong URL. This change also undoes the suppression of rules-based endpoint generation for all services apart from EventBridge, S3, and S3 Control, which was implemented in #3520 because of the previously mentioned hostPrefix issue.

Modifications

• Remove useRuleBasedEndpoints customization, enabling rules based endpoints for all services again.
• Update endpoint interceptors to correctly resolve and add the hostPrefix if necessary
• Update generated client tests to support hostPrefix

Testing

• New unit tests
• Client endpoint tests updated to correctly handle cases where the client adds a hostPrefix to the requests. i.e. if the operation being called has a hostPrefix, the expected URL is updated to also include that hostPrefix.
• Manual verification of some services that use hostPrefix such as location and evidently.
• Running Integ tests

Here's an example generated client test from the location service, where the expected URL is updated so that in includes the geofencing. HostPrefix required for CreateGeofenceCollection.

new SyncTestCase("For region eu-central-1 with FIPS enabled and DualStack enabled", () -> {
                    LocationClientBuilder builder = LocationClient.builder();
                    builder.credentialsProvider(BaseRuleSetClientTest.CREDENTIALS_PROVIDER);
                    builder.httpClient(getSyncHttpClient());
                    builder.fipsEnabled(true);
                    builder.region(Region.of("eu-central-1"));
                    builder.dualstackEnabled(true);
                    CreateGeofenceCollectionRequest request = CreateGeofenceCollectionRequest.builder().build();
                    builder.build().createGeofenceCollection(request);
                }, 
                Expect.builder()
                        .endpoint(Endpoint.builder().url(URI.create("https://geofencing.geo-fips.eu-central-1.api.aws")).build())
                        .build()),

  	},

• Compare to the definition of the test in endpoint-tests.json that does not include the prefix in the expected URL (because it does not know about CreateGeofenceCollectionRequest and its hostPrefix):

  aws-sdk-java-v2/services/location/src/main/resources/codegen-resources/endpoint-tests.json
