test: stop CI tests from downloading tokenizer files and images (#43257)
* test: load the embedding base image from a committed 100x100 PNG instead of downloading it

* test: move the volcengine embedding test into tests/unit

* test: check gpt2 and r50k_base tokenizer parity against committed tiktoken reference files

* test: check hub tokenizer selection against an in-memory Hugging Face hub

* test: serve image URLs from respx in the gemini tool-result and format-param tests

* ci: drop the emptied legacy core-utils test path

* test: cover the cohere and anthropic tokenizer paths in the hub tokenizer test

* test: fetch every format-param image through respx and check its bytes reach the request

* test: drop the gpt2 and r50k_base parity tests, which no litellm path uses

* test: drop comments that restate assertions in the format-param test
