[feature request] consolidation of aws resource detection

[thompson-tomo]

Component

OpenTelemetry.Resources.AWS

Is your feature request related to a problem?

Both the instrumentation.AWSLamba & Resources.AWS packages are providing resource detectors and a user is not even aware of the awslamba resource detector.

What is the expected behavior?

All aws resource detectors reside in the 1 project and hopefully with this the need for shared aws code is diminished/removed.

Which alternative solutions or features have you considered?

N/a

Additional context

The resource detector could be a dependency of the instrumentation if desired
