Alessandro Siniscalchi 60846a081f [parachain-template] runtime API Implementations into mod apis (#3817)
This PR significantly refactors the runtime API implementations to
improve project structure, maintainability, and readability. Key changes
include:

1. **Enhancing Visibility**: Adjusts the visibility of
`RUNTIME_API_VERSIONS` in `impl_runtime_apis.rs` to `pub`, making it
accessible throughout the runtime module.
2. **Centralizing API Implementations**: Introduces a new file,
`apis.rs`, within the parachain template's runtime directory.
3. **Streamlining `lib.rs`**: Updates the main runtime library file to
reflect these structural changes. It removes redundant API
implementations and points `VERSION` to the newly exposed
`RUNTIME_API_VERSIONS` from `apis.rs`, simplifying the overall runtime
configuration.

### Motivations Behind the Refactoring:
- **Improved Project Structure**: Centralizing API implementations in
`apis.rs` offers a clearer, more navigable project structure.
- **Better Readability**: Streamlining `lib.rs` and reducing clutter
enhance readability, making it easier for new contributors to understand
the project layout and logic.

### Summary of Changes:
- Made `RUNTIME_API_VERSIONS` public in `impl_runtime_apis.rs`.
- Added `apis.rs` to centralize runtime API implementations.
- Streamlined `lib.rs` to adjust to the refactored project structure.

Substrate runtime api

The Substrate runtime api is the crucial interface between the node and the runtime. Every call that goes into the runtime is done with a runtime api. The runtime apis are not fixed. Every Substrate user can define its own apis with decl_runtime_apis and implement them in the runtime with impl_runtime_apis.

Every Substrate runtime needs to implement the [Core] runtime api. This api provides the basic functionality that every runtime needs to export.

Besides the macros and the [Core] runtime api, this crates provides the [Metadata] runtime api, the [ApiExt] trait, the [CallApiAt] trait and the [ConstructRuntimeApi] trait.

On a meta level this implies, the client calls the generated API from the client perspective.
