Pull conhost measurements with low/no future relevancy

[miniksa]

After a meeting with the data team, we decided to pull a bunch of the interactivity measurements from conhost.exe that we're not planning on using ever again (primarily because Terminal is becoming/has become the face of user interactivity so we don't need to really measure how people are interacting with conhost.exe anymore to make a decision.)

This represents walking through the events and pulling them. We're still planning on leaving events that may influence feature decisions in the new Terminal (or help us identify people who cannot complete their workflow in Terminal and are stuck on conhost.exe.)
