[feature request] ForceFlush checking succeeded status

Is your feature request related to a problem?

There are some parts in the code that do ForceFlush: https://github.com/open-telemetry/opentelemetry-dotnet-contrib/blob/5aa6d86836bbc13659d61abcf3040a0811537f7e/src/OpenTelemetry.Extensions/Trace/AutoFlushActivityProcessor.cs#L79C18-L79C32

ForceFlush can return false, shouldn't that return value be checked? For example, if you implement AutoFlushActivityProcessor, it might make sense you want more reliability and thus want to check if everything is actually sent.
