instrumentation-document-load doesn't support re-enables

[kkruk-sumo]

What version of OpenTelemetry are you using?

"@opentelemetry/api": "^1.0.2",
"@opentelemetry/instrumentation": "^0.24.0",
"@opentelemetry/instrumentation-document-load": "^0.24.0",
"@opentelemetry/web": "^0.24.0",

What version of Node are you using?

12.7.0

What did you do?

I enabled DocumentLoadInstrumentation twice.

What did you expect to see?

Only one trace with documentLoad span to be created.

What did you see instead?

Two traces were generated.

Additional context

Instrumentations can be disabled and re-enabled in runtime. Other JS instrumentations like XHR or fetch supports re-enabling.
In my opinion the instrumentation-document-load should does nothing after being enabled again.
