* fix(vertex_ai): omit function_call id on Vertex Gemini 3.5+ tool turns

Vertex AI rejects `id` on function_call/function_response parts; only Google AI Studio accepts it for Gemini 3.5+ strict tool matching.

* Update litellm/llms/vertex_ai/gemini/vertex_and_google_ai_studio_gemini.py

* fix(vertex_ai): forward custom_llm_provider in context caching

Pass custom_llm_provider through to _gemini_convert_messages_with_history
in the context caching path so Gemini 3.5+ tool-call `id` forwarding
behaves consistently between cached and non-cached completions on Google
AI Studio.

In total litellm runs 1000+ tests

To make it easier to contribute and map what behavior is tested,

we've started mapping the litellm directory in tests/test_litellm

This folder can only run mock tests.
