Generic skeleton implementation - Only with Event and Black Box Test with IPC_bridge App

[saksham-chawla]

Hi @crimson11
As discussed earler Rasing a pull request containing the Event with black-box tests through Example Application.

Rest will done in second pull request(First week of Feb) which includes the complete Event functionality documentation along with tests for both Event and Field

Generic Skeleton Implementation with Event Support and Black Box Tests

This pull request introduces a generic skeleton implementation, enabling the creation of runtime-configurable service providers that operate on raw data. The initial scope focuses on GenericSkeletonEvent functionality, allowing applications like gateways or bridges to offer services without compile-time knowledge of specific data types. This is achieved through the introduction of DataTypeMetaInfo for dynamic size and alignment information.

The changes involve a significant refactoring of existing event handling logic into a new lola::SkeletonEventCommon class, centralizing shared behavior for both strongly typed and generic events. It also includes the necessary factory interfaces and implementations for creating generic event bindings, along with comprehensive unit tests and an updated example application to demonstrate the new capabilities.
