Felipe Coury d7d526b81d Prepare the telemetry shutdown worker during initialization (#39050) ...

## Why

Creating the telemetry shutdown thread during shutdown can fail under resource
pressure, including when the native thread guard page cannot be allocated.

## What changed

- Start and verify a dedicated shutdown worker when `OtelProvider` is created.
- Send the provider to the prepared worker for bounded shutdown, while preserving
  timeout behavior and avoiding a potentially blocking destructor if worker
  preparation failed.
- Rename the fallible provider constructor to `try_new`.

## Testing

Add Unix regression coverage that injects guard-page allocation failures, plus
coverage for worker preparation failure, successful shutdown, and timeouts.
