Dlopen backend 5 (#779) Major change to the backend that allows for pluggable versions of llama.cpp/ggml. This was squashed merged from dlopen_backend_5 where the history is preserved.

Add llama.cpp support for loading llama based models in the gui. We now support loading both gptj derived models and llama derived models.

add requiredMem method to llmodel impls most of these can just shortcut out of the model loading logic llama is a bit worse to deal with because we submodule it so I have to at least parse the hparams, and then I just use the size on disk as an estimate for the mem size (which seems reasonable since we mmap() the llama files anyway)

First attempt at providing a persistent chat list experience. Limitations: 1) Context is not restored for gpt-j models 2) When you switch between different model types in an existing chat the context and all the conversation is lost 3) The settings are not chat or conversation specific 4) The sizes of the chat persisted files are very large due to how much data the llama.cpp backend tries to persist. Need to investigate how we can shrink this.

Fix up for newer models on reset context. This fixes the model from totally failing after a reset context.

std::vector<Token> tokenize(PromptContext &, const std::string&) const override;
llmodel: change tokenToString to not use string_view (#968) fixes a definite use-after-free and likely avoids some other potential ones - std::string will convert to a std::string_view automatically but as soon as the std::string in question goes out of scope it is already freed and the string_view is pointing at freed memory - this is *mostly* fine if its returning a reference to the tokenizer's internal vocab table but it's, imo, too easy to return a reference to a dynamically constructed string with this as replit is doing (and unfortunately needs to do to convert the internal whitespace replacement symbol back to a space)
