User-defined RequestId for SignalWorkflow

[ndtretyak]

Is your feature request related to a problem? Please describe.
I want to use server-side deduplication for signals. However, RequestId is always set to uuid.New

sdk-go/internal/internal_workflow_client.go

Line 1829 in 9d74a90

RequestId: uuid.New(),

Describe the solution you'd like
An option to override the RequestId in each method, allowing users to specify their own identifier instead of a generated UUID.

Long term server side deduplication of signals by RequestId is not a stable feature users should rely on temporalio/temporal#4021 so it is intentionally not exposed in any SDK. If you want deduplication of signals the best approach is to put your own ID in the signal input and deduplicate in the workflow
