src: factor out Node.js-agnostic N-APIs

Split the Node.js ECMAScript API (N-EAPI?) into its own header and
implementation files. The motivation is that the ECMAScript API stand
on its own so it might be embedded separately, implementation and all.

Portions of the implementation used by both files are stored in
`node_api_impl.h`.

The checked boxes below indicate that the given API remains in
`node_api.h`, whereas the lack of a checkbox indicates that the API was
moved to `node_ecma_api.h`.
