[mattcreaser]

• PR title and description conform to Pull Request guidelines.

Issue #, if available:

Description of changes:

• Remove the @InternalAmplifyApi markers from all AmplifyOuputsData classes.
• Add Amplify.configure(AmplifyOutputsData) API

This allows customers to configure directly in code by instantiating the AmplifyOutputsData:

val outputs = AmplifyOutputsData(
    auth = Auth(
        awsRegion = "us-east-1",
        userPoolId = "...",
        userPoolClientId = "..."
    ),
    storage = Storage(
        awsRegion = "us-east-1",
        bucketName = "myBucket"
    )
)

Amplify.configure(outputs, context)
