Initial Layout for Rocket.Chat Flutter SDK

[yatendra2001]

Description

This PR implements the layout and CI for Rocket.Chat Flutter SDK project as proposed in issue #1 . The project structure, CI/CD setup, and the dummy implementation of tests are included. The main packages created are rocket_chat_embeddedchat_component and rocket_chat_api.

Packages:

• rocket_chat_embeddedchat_component: Will contain the SDK with Flutter UI components for Rocket.Chat, allowing for easy embedding of the chat interface into other Flutter applications.
• rocket_chat_api: Provides the Dart-friendly API/stub for applications requiring in-depth modification of chat behaviour or using the chat engine as a messaging fabric.

Both packages include a sample app which will use the respective libraries to demonstrate the functionality and usage.

CI/CD:

• Added a GitHub Actions workflow for continuous integration, building, and testing.
• Included build scripts and tests for both packages and the sample app.
• The CI/CD will keep evolving as we move further.

Tests:

• Integrated dummy test directory for each package and their corresponding sample apps. This directory will contain unit_tests, integration_tests and widget_tests as we move along.

Need also to make sure the workflows are legit by adding one of the monorepo management tools.

Seems Melos , mono_repo, flutter_monorepo_build_tools or other.

@Sing-Li I've added new .gitignore rules and added Melos as a monorepo management tool. Also, should we make some changes in Readme.md file too?
