fix(aiCore): only apply sendReasoning for openai-compatible SDK providers (#12387)

sendReasoning is a patch specific to @ai-sdk/openai-compatible package.
Previously it was incorrectly applied to all providers in buildGenericProviderOptions,
including those with dedicated SDK packages (e.g., cerebras, deepseek, openrouter).

Now it only applies when the provider will actually use openai-compatible SDK:
- No dedicated SDK registered (!hasProviderConfig(providerId))
- OR explicitly openai-compatible (providerId === 'openai-compatible')
