Related to #3933
The first MSTest version that supported stdout/stderr for MTP in Test Explorer is MSTest 3.6.
This was done in two PRs: #3486 and #3749.
The first PR was a hacky approach that couldn't work for xunit.v3 (see #3740). So a better approach was introduced in the other PR.
When the first testfx PR was done, we followed-up with a corresponding change on Test Explorer side that got in 17.12.
Later on, when the second testfx PR was done, we also followed-up with a change on Test Explorer side that was done also for 17.12.
What we ended up with is two known properties for specifying stdout/stderr, and serializing the information twice. This PR cleans that up.
I also have a similar PR on VSU to clean this up for Test Explorer.
