RUM-12891: Fix RUM resource duration breakdown

[ambushwork]

What does this PR do?

This PRs fixes the resource duration breakdown feature which is broken since the version 2.12.0, more precisely from this commit.

The main cause of issue:

We have DatadogInteceptor generating the RUM event startResource with the ResourceId(requestUrl, randomUUID) as the key of the resource when intercepting a request, also we have DatadogEventListener to add waitForResourceTiming event and addResourceTiming to report the resource timing for this duration breakdown.

The issue is that, both DatadogInteceptor and DatadogEventListener are generating their own UUID for the same request, so in our event processing they won’t be able to match.

The fix is to remove the generation of UUID in DatadogEventListener since its key is only used for enhancing the current resource.
