AWS::Lambda::Function ZipFile - allow inline archives

### Name of the resource

AWS::Lambda::Function

### Resource name

_No response_

### Description

Context: at Pulumi, we use CloudFormation schema's to manage resources via Cloud Control API.

For AWS Lambda Functions, we are looking for a way to upload a function archive directly as a part of the `ZipFile` payload, likely as a zip archive serialized into a string. This would allow users to bypass the extra step of managing an S3 bucket. This functionality is available via the Lambda REST API but apparently not via Cloud Formation.

It would be beneficial to support specifying the bytes of a ZIP file inline, and make sure Cloud Control API turns that into a call to the appropriate Lambda REST API functions without the need to manually manage S3 bucket/object.
