Chat templates are rendered with ImmutableSandboxedEnvironment in transformers so no need to do otherwise here.

* Support multiple chat templates - step 1
As a first step, allow user to to select template from metadata with chat_format parameter in the form of `chat_template.name`.
* register chat templates to self.chat_formats instead of globally
* Don't expose internal chat handlers yet

* Proper fill-in-middle support
Use prefix/middle/suffix tokens when metadata is present in GGUF, like f.ex. in [this](https://huggingface.co/CISCai/CodeQwen1.5-7B-Chat-SOTA-GGUF) one.
* fall back to internal prefix/middle/suffix id
In some cases llama.cpp will make a guess at fim tokens, use them if there's no metadata.
* typo--
* don't insert special tokens that are not there in suffix
Note: add_bos is misnamed, it's actually add_special and can cause several special tokens to be added to the token list (the special parameter is actually parse_special).
* don't add/parse any special tokens when using fim
I've left original behavior when no fim tokens are found, but this should perhaps be re-evaluated.
* don't append suffix to prompt_tokens unless fim tokens are detected
* make sure we only do this for fim
