[Feature]: Split AssertLib Functionality From DebugLib

### Feature Overview

Today, assert functionality lives inside of DebugLib, which is mixing two separate features into one library and requires every DebugLib implementation to change in response to changes to assert functionality.

### Solution Overview

A cleaner and more maintainable architecture would be to split the assert functionality into an AssertLib with a well defined interface that can be consumed by DebugLib.
