This change:
- Introduces the LocalEvalService Class.
- Implements only the "perform_inference" method. Evaluate method will be implemented in the next CL.
- Adds required test coverage.

This change integrates the plugin system with ADK. PluginManager is attached to the invocation context similar to session/artifact/memory.
It includes integrations with following ADK internal callbacks:
* App callbacks: Integrated in the BaseRunner class, in run_async and run_live
* On Message callbacks: Integrated in the BaseRunner class, triggers on run_async.
* Agent callbacks: Integrated in the BaseAgent class. Leveraging the existing *callback functions
* Model callbacks: Integrating in the base_llm_flow.
* Tool callbacks: Integrated in functions.py, wrapped around the code for agent tool_callbacks
Sample code to use plugins:
```python
# Add plugins to Runner
runner = Runner(
app_name="my-app",
agent=root_agent,
artifact_service=artifact_service,
session_service=session_service,
memory_service=memory_service,
plugins=[
MySamplePlugin(),
LoggingPlugin(),
],
)
```

Plugin is a collection of callbacks (lifecycle hooks), including callbacks for Agent, Tools, Model and App. It helps developers to add customizations and change behaviors of their agent application easily
This is the first change that introduces only the base interfaces based on the doc.
plugins folder is generated with `create_symlink.sh plugins`

Even though InMemoryMemoryService is intended only for testing and local development, we eliminate a potential source of bugs during prototyping by providing a thread-safe InMemoryMemoryService.

- Allow run_async to break on partial events instead of raising ValueError
- Generate aggregated streaming content regardless of finish_reason
- Add error_code and error_message to final streaming responses if model response is interrupted.

This commit includes a number of new tests for live streaming with function calls. These tests cover various scenarios:
- Single function calls
- Multiple function calls
- Parallel function calls
- Function calls with errors
- Synchronous function calls
- Simple streaming tools
- Video streaming tools
- Stopping a streaming tool
- Multiple streaming tools simultaneously
The tests use mock models and custom runners to simulate the interaction between the agent, model, and tools. They verify that function calls are correctly generated, executed, and that the expected data is returned.

This would allow users to easily make a copy of the agents they built without having to add too much boilerplates. This promotes code reuse, modularity and testability of agents.
