What is the expected workflow for Symbols Validation of official releases?

### Description

We were looking at the results of https://dev.azure.com/dnceng/internal/_build?definitionId=1303&_a=summary and see many failures.

Who's meant to review these and file issues or follow up on the failures? @michalpavelka @mmitche

We noticed many symbol failures but it's hard to know if those are real problems or issues with the pipeline.

### Reproduction Steps

Examine failures in https://dev.azure.com/dnceng/internal/_build?definitionId=1303&_a=summary

### Expected behavior

Most release builds are green - for any failures issues are filed.

### Actual behavior

Many failing validation checks, unclear if they are actionable failures or not.

### Regression?
