CloudWatch Widget: Support time range value

[Amri91]

As per CDK documentation, there is no way to define a widget that looks like this.

{
    "view": "singleValue",
    "region": "us-east-1",
    "metrics": [
        [someMetric]
    ],
    "setPeriodToTimeRange": true // <--
}

Use Case

I want to display a widget on my CloudWatch dashboard that uses my Route53 health checks to show a rudimentary uptime. Currently, I have to use the console to switch the widgets to use time range value instead of setting it using my current CDK code.

Proposed Solution

Add a new property in the SingleValueWidgetProps and use it in the SingleValueWidget toJson function.
