Description

The following issue reports an error that occurs when calling an API that takes the Date type as a parameter, such as GetMetricData API, from a Custom Resource Lambda function, where the parameter is passed as string type to the AWS SDK.
#27962
https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/client/cloudwatch/command/GetMetricDataCommand/#:~:text=Description-,EndTime,-Required

To resolve this error, the string type must be properly converted to Date type when calling the AWS SDK from Lambda.
In this PR, I added the conversion to Date type in the same way as the existing conversion to number and Uint8Array types.
Uint8Array: #27034
number: #27112

Major changes

update-sdkv3-parameters-model.ts script

If the type is timestamp in the smithy specification, write d to the state machine so that it can be converted to a Date type later.

update-sdkv3-parameters-model.sh script was not called from anywhere, so I called it manually and updated the JSON file.
Please let me know if there is a problem.

sdk-v2-to-v3-adapter module

I added code to convert value marked d in state machine to Date type.
If the conversion to Date type fails, the Date class does not throw an exception, so the error is handled in a slightly tricky way.
Also added a unit test for this process.

integ-tests-alpha module

Added integ-test to verify that errors reported in the related issue have been resolved.
The IAM Policy added internally by the call to adPolicyStatementFromSdkCall looks like the following and does not call GetMetricData correctly, so the addToRolePolicy method was used to explicitly add a new Policy is added explicitly with the addToRolePolicy method.
