Telemetry instances displaying <blank> in multiple fields

[danielayala94]

Problem Description

Surprisingly, many telemetry instances are showing <blank> data in fields that I'd initially assume to be always populated. Examples:

JS Engine project: Chakra or Hermes - it has to be either, but some show <blank> ResultCode: Success or failure (if it is, tell the error code), but some show <blank>

Steps To Reproduce

Look at the telemetry dashboard, measures clearly show different proportions of <blank> instances, depending on the measure.

Expected Results

I would not expect any <blank> instances at all.

@danielayala94 Possible this is by design on the upstream side. If you confirm, resolve this issue appropriately.

It's possible we don't have a fallback for the property not being set, or our code to capture msbuild properties for telemetry. Probably in packages\@react-native-windows\telemetry\src\telemetry.ts or one of the nearby utility modules.
