[receiver/awsxray] Set cloudwatch logs metadata in attributes

[jefchien]

Description:

From the issue:

X-Ray segments have a few optional fields that carry AWS resource data. As part of the translation of X-Ray segments to spans, the translator extracts AWS data and puts them in the resource attributes. It does this for EC2, ECS, Beanstalk, and EKS, but not for CloudWatch Logs. So, by the time the span reaches the exporter, that information is lost.

This change adds the cloudwatch logs metadata to the attributes with the keys conventions.AttributeAWSLogGroupARNs and conventions.AttributeAWSLogGroupNames. Both of these are used by the awsxrayexporter to restore the LogGroupMetadata.

	case conventions.AttributeAWSLogGroupNames:
	logGroups = normalizeToSlice(value)
	case conventions.AttributeAWSLogGroupARNs:
	logGroupArns = normalizeToSlice(value)

Lines 293 to 295 in decc66f

	// Given an array of log group ARNs, create a corresponding amount of LogGroupMetadata objects with log_group and arn
	// populated, or given an array of just log group names, create the LogGroupMetadata objects with arn omitted
	func getLogGroupMetadata(logGroups pcommon.Slice, isArn bool) []awsxray.LogGroupMetadata {

Link to tracking Issue: Fixes #31784

Testing: Added unit tests to validate the translation to attributes.

I've filed #32275 for the failing integration test, it doesn't appear to be related to your changes.

This looks good to me, but I'd like a code owner or someone with more AWS experience to review as well, I'm not very familiar here 👍
