Fix issue of multiple instances of OpenTelemetry-Instrumentation EventSource being created

[utpilla]

Similar to #4586

We have multiple projects that link to InstrumentationEventSource which could cause users to run into the error: An instance of EventSource with Guid {guid} already exists. These components should use their own dedicated EventSource events.

Changes

• Removed IntrumentationEventSource
• Update the instrumentation libraries to use their own EventSource events
