Submit initial UXP conformance results

https://github.com/upbound/universal-crossplane/

Upbound Universal Crossplane (UXP) is Upbound's official enterprise-grade distribution of Crossplane. It's fully compatible with upstream Crossplane, open source, capable of connecting to Upbound Cloud for real-time dashboard visibility, and maintained by Upbound. It's the easiest way for both individual community members and enterprises to build their production control planes.

We'd like to submit conformance test results to demonstrate that UXP 1.2.x is a conformant distribution of Crossplane 1.2.x.
