Make it possible to generate regression tests for Flipper plugins

Summary:
This Pull request makes it possible to automatically generate regression tests for plugins. The idea here is to record all incoming states for a specific plugin, the start state of the plugin, and the enstate of the plugin.

By replaying the same events in a test, the same plugin should result in the same end state. This will make it easy to test regressions and refactorings on real life scenarios. Execution time is recorded as well.

The API's are exposed as

- `flipperStartPluginRecording()`
- `flipperStopPluginRecording()`

This process generates both a data snapshot and unit test.
