Cesar Garcia a037414985 feat(deepseek): add native support for thinking and reasoning_effort params (#17712)
* feat(deepseek): add native support for thinking and reasoning_effort params

Add proper parameter mapping for DeepSeek thinking mode, allowing users
to use the unified LiteLLM interface instead of extra_body workarounds.

Supported formats:
- thinking={"type": "enabled"}
- thinking={"type": "enabled", "budget_tokens": X} (budget_tokens ignored)
- reasoning_effort="low|medium|high" (maps to thinking enabled)

DeepSeek only supports {"type": "enabled"} without budget_tokens,
so any budget_tokens are stripped and all reasoning_effort values
(except "none") map to enabled.
