Async WebAssembly compilation was implemented by adding two
bindings: `set_wasm_streaming_callback`, which registered a callback to
be called whenever a streaming wasm compilation was started, and
`wasm_streaming_feed`, which let the JS callback modify the state of the
v8 wasm compiler.
`set_wasm_streaming_callback` cannot currently be implemented as
anything other than a binding, but `wasm_streaming_feed` does not really
need to use anything specific to bindings, and could indeed be
implemented as one or more ops. This PR does that, resulting in a
simplification of the relevant code.
There are three operations on the state of the v8 wasm compiler that
`wasm_streaming_feed` allowed: feeding new bytes into the compiler,
letting it know that there are no more bytes coming from the network,
and aborting the compilation. This PR provides `op_wasm_streaming_feed`
to feed new bytes into the compiler, and `op_wasm_streaming_abort` to
abort the compilation. It doesn't provide an op to let v8 know that the
response is finished, but closing the resource with `Deno.core.close()`
will achieve that.

No user impact, but is simpler and aligns with `opcall()`

Because it was possible to disable those with a runtime flag, they were
not available through primordials. The flag has since been removed
upstream.

* refactor(ops): return BadResource errors in ResourceTable calls
Instead of relying on callers to map Options to Results via `.ok_or_else(bad_resource_id)` at over 176 different call sites ...

Oneshot is more appropriate because mod_evaluate() only sends a single
value.
It also makes it easier to use it correctly. As an embedder, I wasn't
sure if I'm expected to drain the channel or not.

This commit changes return type of JsRuntime::execute_script to include
v8::Value returned from evaluation.
When embedding deno_core it is sometimes useful to be able to inspect
script evaluation value without the hoops of adding ops to store the
value on the OpState.
v8::Global<v8::Value> is used so consumers don't have to pass
scope themselves.

(#11200)
The WebAssembly streaming APIs used to be enabled, but used to take
buffer sources as their first argument (see #6154 and #7259). This
change re-enables them, requiring a Promise<Response> instead, as well as
enabling asynchronous compilation of WebAssembly modules.

This commit introduces primordials to deno_core. Primordials are a
frozen set of all intrinsic objects in the runtime. They are not
vulnerable to prototype pollution.

This commit adds support for Atomics and FinalizationRegistry by integrating
V8's message loop into "JsRuntime::poll_event_loop".

This commit changes implementation of module loading in "deno_core"
to track all currently fetched modules across all existing module loads.
In effect a bug that caused concurrent dynamic imports referencing the
same module to fail is fixed.

This commits moves implementation of net related APIs available on "Deno"
namespace to "deno_net" extension.
Following APIs were moved:
- Deno.listen()
- Deno.connect()
- Deno.listenTls()
- Deno.serveHttp()
- Deno.shutdown()
- Deno.resolveDns()
- Deno.listenDatagram()
- Deno.startTls()
- Deno.Conn
- Deno.Listener
- Deno.DatagramConn

This commit adds support for piping console messages to inspector.
This is done by "wrapping" Deno's console implementation with default
console provided by V8 by the means of "Deno.core.callConsole" binding.
Effectively each call to "console.*" methods calls a method on Deno's
console and V8's console.
