[Bug]: Cross thread access to the static dictionary

[f-alizada]

Updating properties of the static class could be accessed from different threads which could cause corruptions:

msbuild/src/Build/BackEnd/BuildManager/BuildManager.cs

Line 580 in b0e2b79

loggingService.LogTelemetry(buildEventContext: null, KnownTelemetry.LoggingConfigurationTelemetry.EventName, KnownTelemetry.LoggingConfigurationTelemetry.Properties);

FYI @rokonec - related #8561?

Closing since the PR got merged already.
