Required properties and Circular Dependencies

## Problem Statement
AutoFac can resolve circular dependencies when PropertiesAutoWired = true but it cannot when using required properties.

This seems like a minor oversight on the required properties implementation. Injecting into required properties should be able to resolve circular dependencies.

## Desired Solution
AutoFac can resolve circular dependencies for required properties.

## Alternatives You've Considered
Leave things as-is.

## Additional Context

No files, tests, or entry points are named. Start by locating the required-properties injection path and the existing PropertiesAutoWired handling for circular dependencies. Done means adding coverage for circular dependencies through required properties and confirming the behavior matches the existing supported path.
