feat(synthetics): add activeTracing, memory and timeout property to Canary class (#30556)

### Issue # (if applicable)

Closes #9300, #14086, #28152

### Reason for this change
In order to make the properties in the [runConfig](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_synthetics.CfnCanary.RunConfigProperty.html) of the L1 Construct configurable in the L2 Construct.

* [activeTracing](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_synthetics.CfnCanary.RunConfigProperty.html#activetracing)
* [memoryInMb](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_synthetics.CfnCanary.RunConfigProperty.html#memoryinmb)
* [timeoutInSeconds](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_synthetics.CfnCanary.RunConfigProperty.html#timeoutinseconds)

At the moment, the L2 [Canary](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_synthetics.Canary.html) Class only supports [environmentVariables](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_synthetics.CfnCanary.RunConfigProperty.html#environmentvariables) in the `runConfig`.



### Description of changes
Add missing properties.

* `activeTracing`
* `memory`
* `timeout`

Note:  The following is stated in #9300, but when tested, it was possible to set only `memoryInMb` (`memory`).

> The difficulty is that timeoutInSeconds is required if runConfig is set, so one cannot only specify memoryInMb.

Test code is here.

```ts
class TestStack extends Stack {
  constructor(scope: Construct, id: string, props?: StackProps) {
    super(scope, id, props);

    new synthetics.Canary(this, 'Canary', {
      canaryName: 'next',
      runtime: synthetics.Runtime.SYNTHETICS_NODEJS_PUPPETEER_7_0,
      test: synthetics.Test.custom({
        handler: 'index.handler',
        code: synthetics.Code.fromInline(`
          exports.handler = async () => {
            console.log(\'hello world\');
          };`),
      }),
      cleanup: synthetics.Cleanup.LAMBDA,
      memory: Size.mebibytes(2048),
    });
  }
}
```



### Description of how you validated changes
Add unit tests and integ tests.
