(asset): Create an `Asset` from a JS object (POJO)

### Describe the feature

I would like to be able to create an asset from a plain JS object.

### Use Case

## Generic

Include a large JS object as part of the deployment, so that it can then be used in a Custom Resource handler.

## Specific

We are working on an OpenSearch construct that interacts with the OpenSearch domain.

This construct has methods that _do things_, such as create an index map or can even, potentially, add data to the index (seed data).

These objects are arbitrary in size, and are not suitable for Custom Resource parameter passing.

The idea is to create an asset from this object (props), and then pass it as the CR prop to the handler.

### Proposed Solution

Similar to how S3 Deployment construct works, but for generic assets.

### Other Information

Roll our own.

- [X] I may be able to implement this feature request
- [ ] This feature might incur a breaking change

### Environment details (OS name and version, etc.)

N/A

No files, tests, or entry points are named. Start by reviewing the linked S3 Deployment supported-sources documentation and the existing Custom Resource asset flow; done means a plain JavaScript object can become a generic asset and be passed to a handler as a custom-resource property.
