Add support for windowseventlog receiver for ADOT collector

[git-jayj]

Is your feature request related to a problem? Please describe.
It is very common use case to collect Windows Event Logs from EC2 instances running Windows workload and forward them to CloudWatch log groups for further analysis/alerting.

Describe the solution you'd like
Now that we have support for logs in ADOT collector this can be a useful enhancement to support windowseventlog receiver so that customer can collect and send the events to CloudWatch Log groups using awscloudwatchlogsexporter.

Describe alternatives you've considered
Alternative is to use CloudWatch agent instead of ADOT collector as it already supports this. Building a custom collector is another option, but it could introduce additional complexity and maintenance overhead for users.

Additional context
I see that most of the other vendors(e.g. splunk, honeycomb etc.) supports windowseventlog receiver.
