SemanticKernel: Correcting non-standard way of working with PromptExecutionSettings

Optimize Semantic Kernel LLamaSharpChatCompletion when running with StatefulExecutorBase models

Optional IHistoryTransform added to ChatSession.InitializeSessionFromHistoryAsync

Optional IHistoryTransform added to ChatSession.InitializeSessionFromHistoryAsync

ChatSession.InitializeSessionFromHistoryAsync now accepts IHistoryTransform as an optional parameter.

ci: add workflow to check the spellings.

Add LLaMA3 chat session example.

LLava Async Loading

- Fixed checking for invalid handles in `clip_model_load`

Interruptible Async Model Loading With Progress Monitoring

can be used downstream to post-process the messages based on the requested format

- Async loading supports cancellation through a `CancellationToken`. If loading is cancelled an `OperationCanceledException` is thrown.  If it fails for another reason a `LoadWeightsFailedException` is thrown.
 - Updated examples to use `LoadFromFileAsync`

Fix typo in issue templates.

Add issue templates.

Removed Unnecessary Constructor From Safe Handles

Empty batch check

Slightly Safer Quantize Params

- Passing model path, instead of a message, to `LoadWeightsFailedException` constructor

- Returning SafeLLamaGrammarHandle directly from `llama_grammar_init` and `llama_grammar_copy`

The extension of PromptExecutionSettings is not only for ChatCompletion, but also for text completion and text embedding.

* Added the ability to save and load individual conversations in a batched executor.
 - New example
 - Added `BatchedExecutor.Load(filepath)` method
 - Added `Conversation.Save(filepath)` method
 - Added new (currently internal) `SaveState`/`LoadState` methods in LLamaContext which can stash some extra binary data in the header

* Added ability to save/load a `Conversation` to an in-memory state, instead of to file.

* Moved the new save/load methods out to an extension class specifically for the batched executor.

* Removed unnecessary spaces
