Add Hermes Root API in all other versions of Hermes (#51082)

Summary:
Pull Request resolved: #51082

Introduces the `IHermesRootAPI` interface and a class implementation.
This root API will contain the previously static methods on
`HermesRuntime`.

The root API will serve as an entry point for users to create the Hermes
runtime and invoke methods that do not necessarily require a runtime.

Diff also moves all usages of the static methods on `HermesRuntime` to
getting the methods from the root API.

Multiple places are depending on Hermes, Hermes snapshot, and Shermes,
so this diff will also update all of these verions of Hermes at once.
