Description

Is your feature request related to a problem? Please describe.
SignalExternalWorkflowExecutionCommandAttributes.ChildWorkflowOnly is not exposed as a part of any JavaSDK API.
It's also not in the parameters of signal interceptors.

Describe the solution you'd like
We should productize on how this flag should be exposed to the user's code. A specific usecase when settings this flag to true is also needed and will be helpful for documentation purposes.

Additional context
Parity between SDKs. Go and Typescript SDKs expose this flag as a part of their interceptor implementations.

Research direction

Start by inspecting SignalExternalWorkflowExecutionCommandAttributes.ChildWorkflowOnly and the Java signal interceptor parameters, then compare how the Go and TypeScript SDKs expose the flag. The issue does not name files or tests, so first determine the intended Java API and a concrete use case. Done means the exposure is agreed and implemented with supporting documentation.
