Use auto-instrumentation SDK in global tracing (#5920)

Browse Source 
When the auto-instrumentation attaches to a process using the global
TracerProvider, and there has not been a delegate set, create a span
from the go.opentelemetry.io/auto/sdk package so the OTel Go
auto-instrumentation can instrument the application by default.

Resolve #5702
