Implement Ecs::Graphics APIs and Component Ids for the C API

[DynamicField]

Rendering has always been a missing part in the C API. This PR fixes this and adds all methods required to get sprites on the screen.

This PR implements:

• A FutureResult equivalent for the C API
• Methods for the DefaultRenderingSystem, related to textures and entities
• TextureInfo support
• Methods to retrieve component ids of all built-in components
• C struct equivalents for all built-in components

This PR fixes:

• #405

Concerns:

• Is the new LifetimeExtender.h going to work well since we have global static stuff going on?
• Should we make it clear for the user that TextureInfo (among other objects) aren't really "created" and "destroyed" per se, but rather tracked using LifetimeExtender.h with a ConcurrentSharedPtr?
• Is error handling good enough in NrtFutureResult and NrtTextureInfo?
• It looks like Audio already got some components-related code going on. In the future, how should we harmonise the C API for manipulating components?

Stuff to do:

• [ ] Write some tests (which parts to test?)
• [ ] Review the code
