This commit rewrites deno_core::JsRuntime to not implement Future
trait.
Instead there are two separate methods:
- JsRuntime::poll_event_loop() - does single tick of event loop
- JsRuntime::run_event_loop() - runs event loop to completion
This commit renames occurrences of "isolate" variable name
to "js_runtime". This was outstanding debt after renaming
deno_core::CoreIsolate to JsRuntime.
This changes the signature of InspectorSession.post_message to take a
&str rather than a String avoiding the need call str.to_string at each
call site.
This commit fixes implementation of top level await in "deno_core".
Previously promise returned from module execution was ignored causing to execute
modules out-of-order.
With this commit promise returned from module execution is stored on "JsRuntime"
and event loop is polled until the promise resolves.
This makes use of a default referrer when its empty in repl mode so that
dynamic imports work in the global evaluation context.

This ports the REPL over to Rust and makes use of an inspector session to run a REPL on top of any isolate which lets make full use of rustylines various things like validators and completors without having to introduce a bunch of hard to test internal ops and glue code.
An accidental but good side effect of this is that the multiple line input we previously had is now an editable multi-line input prompt that is correctly stored in the history as a single entry.
This extracts the inspector session specific bits from CoverageCollector
into a standalone struct dubbed `InspectorSesssion` which can be used as
a general purpose session to communicate with the inspector on the same
thread as an isolate/inspector pair lives on.
Previously when we used the websocket to talk to the inspector we used
the runtime domain to send a "runIfWaitingForDebugger" message.
However this is not required since we now talk to the inspector directly
and no longer send said message so this removes the enabling of the
domain entirely.
