This provides: - `eio_js_backend`, a simple backend; - `js_of_ocaml-eio`, a counterpart to `js_of_ocaml-lwt`; - `eio_brr`, Eio support for Brr (Eio variants of Brr functions that returns directly instead of returning a future).

This provides:
eio_js_backend, a simple backend;js_of_ocaml-eio, a counterpart tojs_of_ocaml-lwt;eio_brr, Eio support for Brr (Eio variants of Brr functions that returns directly instead of returning a future).This has been heavily inspired by #405. Compared to this PR, there is a clear separation between the scheduler and the JavaScript bindings. Also, it is possible to use Eio from JavaScript callbacks (e.g. from event handlers) as was attempted in #534.
The scheduler is quite different from other Eio backends. It provides a
startfunction that starts executing asynchronously a function in a context where Eio effects can be performed instead of a blockingrunfunction. Indeed, one cannot block waiting for events in JavaScript but one needs to return to the JavaScript event loop. Thestartfunction can be called in JavaScript callbacks to use Eio.eio_jsoois not complete yet.
