In case JavaScript throws an unhandled error, part of the "shared_queue" could
be still unprocessed.
If this is the case; throw the js runtime error instead of asserting on the
queue size not being 0.

This commit rewrites implementation of "JsRuntime::mod_evaluate".
Event loop is no longer polled automatically and users must manually
drive event loop forward after calling "mod_evaluate".

* remove "ModuleNameMap", instead define that map inline inside "Modules" struct
* remove "dyn_import_id" argument from "mod_instantiate"
* rename "Modules" struct to "ModuleMap"
* rename "JsRuntime::modules" to "JsRuntime::module_map"

This commit rewrites "JsRuntime::poll" function to fix a corner case that
might caused "overflown_response" to be overwritten by other overflown response.
The logic has been changed to allow returning multiple overflown response
alongside responses from shared queue.

This commit adds two new "Deno.core" APIs:
- "Deno.core.serialize"
- "Deno.core.deserialize"
These APIs are used to provide structured cloning of values
and will be used for further web worker implementation.

This PR makes json_op_sync/async generic to all Deserialize/Serialize types
instead of the loosely-typed serde_json::Value. Since serde_json::Value
implements Deserialize/Serialize, very little existing code needs to be updated,
however as json_op_sync/async are now generic, type inference is broken in some
cases (see cli/build.rs:146). I've found this reduces a good bit of boilerplate,
as seen in the updated deno_core examples.
This change may also reduce serialization and deserialization overhead as serde
has a better idea of what types it is working with. I am currently working on
benchmarks to confirm this and I will update this PR with my findings.

Preventing V8 from logging erroneous line numbers. Use wasm.

This commit rewrites initialisation of the "shared queue" and
in effect prevents from double execution of "core/core.js" and
"core/error.js".
Previously both of these files were executed every time a "JsRuntime"
was created. That lead to a situation where one copy of each script
was included in the snapshot and then another copy would be
executed after loading the snapshot.
Effectively "JsRuntime::shared_init" was removed; instead execution
of those scripts and actual initialisation of shared queue
was split into two helper functions: "JsRuntime::js_init" and
"JsRuntime::share_queue_init".
Additionally stale TODO comments were removed.

Fixes the following runtime error for me when benchmarking:
thread 'main' panicked at 'called `Result::unwrap()` on an `Err`
value: Error: Unregistered error class: "Error"
Connection reset by peer (os error 104)
Classes of errors returned from ops should be registered via
Deno.core.registerErrorClass().

This reverts commit e924bbdf3606e83ff9eef3a8ed640c4ecc34444f.

Implementors of `deno_core::JsRuntime` might want to do additional actions
during each turn of event loop, eg. `deno_runtime::Worker` polls inspector,
`deno_runtime::WebWorker` receives/dispatches messages from/to worker host.
Previously `JsRuntime::mod_evaluate` was implemented in such fashion that it
only polled `JsRuntime`'s event loop. This behavior turned out to be wrong
in the example of `WebWorker` which couldn't receive/dispatch messages because
its implementation of event loop was never called.
This commit rewrites "mod_evaluate" to return a handle to receiver that resolves
when module's promise resolves. It is now implementors responsibility to poll
event loop after calling `mod_evaluate`.
