Major modules refactoring

[GuilhermeF03]

Summary

In order to make canopy as expansible as possible, we'll need to separate it into three groups of modules:

Engine
A single core module that groups all core part of the system

Here are present all platform-agnostic logic, as well as interfaces to be implemented by distinct platforms

Note

Input, Data, Core, Logging and Core App were moved together, as they all make part of the core of the whole engine

Platforms
Platform-specific implementations

Here we implement platform specific implementations on systems like input, audio, etc...

We also group platform-specific modules here, like physics or graphics.

Note

If mulitple platforms share the same implementations, we might group them later, such as libgdx/core, libgdx/desktop, libgdx/android, etc...

Tooling
Here are all miscellaneous modules, such as devtools and utils.

Note

Compatibility with previous version: Other than imports and build.gradle.kts updates,

How to Test

Same as before:

1. ktlint-format, clean, build, publish, run demo
2. Demo should print normally
