Set GPULayerCount to default value (20) to execute UnitTest. In the case of Release Execution on MacOS set the value to ZERO to disable METAL on MacOS and be able to execute it in CI.
* Updated binaries, using [this build](https://github.com/SciSharp/LLamaSharp/actions/runs/8654672719/job/23733195669) for llama.cpp commit `f7001ccc5aa359fcf41bba19d1c99c3d25c9bcc7`.
- Added all new functions.
- Moved some functions (e.g. `SafeLlamaModelHandle` specific functions) into `SafeLlamaModelHandle.cs`
- Exposed tokens on `SafeLlamaModelHandle` and `LLamaWeights` through a `Tokens` property. As new special tokens are added in the future they can be added here.
- Changed all token properties to return nullable tokens, to handle some models not having some tokens.
- Fixed `DefaultSamplingPipeline` to handle no newline token in some models.
* Moved native methods to more specific locations.
- Context specific things have been moved into `SafeLLamaContextHandle.cs` and made private - they're exposed through C# properties and methods already.
- Checking that GPU layer count is zero if GPU offload is not supported.
- Moved methods for creating default structs (`llama_model_quantize_default_params` and `llama_context_default_params`) into relevant structs.
* Removed exception if `GpuLayerCount > 0` when GPU is not supported.
* - Added low level wrapper methods for new per-sequence state load/save in `SafeLLamaContextHandle`
- Added high level wrapper methods (save/load with `State` object or memory mapped file) in `LLamaContext`
- Moved native methods for per-sequence state load/save into `SafeLLamaContextHandle`
* Added update and defrag methods for KV cache in `SafeLLamaContextHandle`
* Updated submodule to `f7001ccc5aa359fcf41bba19d1c99c3d25c9bcc7`
* Passing the sequence ID when saving a single sequence state
FixedSizeQueue:
- Enqueue would always stop one short of filling the capacity
- Fill would only _replace_ existing items. It was only used in a place where there were not existing items! Removed the method entirely.
LLamaGrammarElement:
- Converted into a `record` struct, removed all of the (now unnecessary) equality stuff.
- Made all the mechanics of grammar parsing (GBNFGrammarParser, ParseState) internal. Just call `Grammar.Parse("whatever")`.
- Added a `GrammarRule` class which validates elements on construction (this allows constructing grammar without parsing GBNF).
- It should be impossible for a `GrammarRule` to represent an invalid rule.
- Equality, hashing etc all implemented automatically
- Default values are defined in just one place (the properties) instead of the constructor as well
- Added test to ensure that serialization works properly
