refactor: moved sdk classes to datapipelines module

[mrehan27]

part of MBL-214

Background

Since Kotlin extensions do not work the same way as Swift, keeping CustomerIO SDK files in core module and adding extensions in the datapipelines module poses challenges for customers. Kotlin users need to import an extension for every method, while the syntax for Java users becomes even more complicated. To address this, we decided to move CustomerIO class to datapipelines module for now. With the planned introduction of EventBus, we do not foresee the need for usage of CustomerIO directly from core elsewhere. In case the need arise in future, we can reevaluate and find alternatives to maintain better customer experience when integrating the SDK.

Changes

• Moved CustomAttributes to core so it can be reused by all modules
• Moved CustomerIO and CustomerIOInstance classes from core module to datapipelines module
• Updated API classes
