Greengrass IPC model update

What's Changed

• Update Greengrass V2 IPC models by @MikeDombo in #450

Full Changelog: v1.18.3...v1.18.4

Eventstream client fix

• Fixes an issue where the eventstream client would close the connection if it received data from an old stream. There is no mechanism to ensure there is no inbound data in transit at the time it closes its end of a stream, so the client instead ignores stale messages.

Greengrass IPC API refactor

This release contains a compile-time breaking change.

• This release contains a refactor of the Greengrass IPC APIs. The factories returning the operation by value as well as the unique_ptr variants have been removed. All operation factories now return a shared_ptr to the operation. This refactor was necessary to correct multiple memory management issues with the previous API contract. Transitioning to the new APIs should be a simple type change in the caller.

Update PubSub sample

• Add the device advisor scripts to enable GitHub Actions to automatically run device advisor test
• Split the PubSub sample down into smaller, connection focused samples
• Updated docs
