Add OS and Process Architecture

[marcpopMSFT]

Description

During our discussions around arm64 it became clear that we weren't sure how often customers use an SDK that doesn't match their current OS. Adding this will help us answer that question so we know whether to prioritize this or not.

Regression?

No

Risk

Low, no functional change.

For performance measurements, I ran dotnet build --help 100 times in a row with and without the change which triggers on telemetry call. I found it 109 seconds with the change and 108 seconds without for a slowdown of ~10ms potentially.
