feat(cloudfront-origins): extend readTimeout maximum value for `Htt…

…pOriginProps` (#18697)

This pull request extends the maximum value of the `readTimeout` property for `HttpOriginProps` up to 180 seconds. This allows the use of the construct also in the case that a limit increase has been approved for CloudFront [origin request timeout quota](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/cloudfront-limits.html#limits-web-distributions).

The 180 seconds cap should be AWS hard limit for that quota.

Closes #18628

+Note that the `readTimeout` property can extend its value over 60 seconds only if a limit increase request for CloudFront origin response timeout

 Origins can also be created from any other HTTP endpoint, given the domain name, and optionally, other origin properties.
