Took the opportunity also to copy the logic to TF, so it can also handle eos_token_id as a list 👀

What does this PR do?
Some bug fixing in advance of #21007 (PR that adds generation config to Flax), to ensure we start from a functional flax generate codebase.
In particular:
pad_token_idwhen it isNoneandeos_token_idis notNone, like TF and PT do. This is very helpful for open text generation examples, like with GPT2, was an open request (Generating with Flax fails when using Causal Language models #18884), and was one of the causes for failure in the existing example. This also includes the recent changes of Add custom stop token ids for generation #20727, whereeos_token_idcan be a list of tokens.int32type specification was missing in the special tokens -- when converted to JAX variables, JAX assumed they werefloat32;
