After internal conversation decided that we will aggregate the new events on the SDK side and fire only one event per build. |

There was a problem hiding this comment.
This LGTM from a functional perspective - but it should be targeted against release/10.0.1xx.

Fixes dotnet/msbuild#12507
Changes:
In MSBuild: Adding MSBuild project level telemetry collecting task host and task factories usage
In SDK: Adding new telemetry events processing to SDK
Telemetry events are sent per project build in MSBuild and then aggregated on SDK side.
Testing:
SDK part - unit tests
MSBuild part - manual testing, compared reported numbers to what is available in binlog, they seem to be correct
