d523cc2abc fix(fetch): Fix uncaught rejection panic with WebAssembly.instantiateStreaming (#13925)
When an exception is thrown during the processing of streaming WebAssembly,
`op_wasm_streaming_abort` is called. This op calls into V8, which synchronously
rejects the promise and calls into the promise rejection handler, if applicable.
But calling an op borrows the isolate's `JsRuntimeState` for the duration of the
op, which means it is borrowed when V8 calls into `promise_reject_callback`,
which tries to borrow it again, panicking.

This change changes `op_wasm_streaming_abort` from an op to a binding
(`Deno.core.abortWasmStreaming`). Although that binding must borrow the
`JsRuntimeState` in order to access the `WasmStreamingResource` stored in the
`OpTable`, it also takes ownership of that `WasmStreamingResource` instance,
which means it can drop any borrows of the `JsRuntimeState` before calling into
V8.

fix(core): Don't override structured clone error messages from V8 (#13942)
In the implementation of structured serialization in
`Deno.core.serialize`, whenever there is a serialization error, an
exception will be thrown with the message "Failed to serialize
response", even though V8 provides a message to use in such cases.
This change instead throws an exception with the V8-provided message,
if there is one.

feat: Add support for import assertions and JSON modules (#12866)
This commit adds proper support for import assertions and JSON modules.

Implementation of "core/modules.rs" was changed to account for multiple possible
module types, instead of always assuming that the code is an "ES module". In
effect "ModuleMap" now has knowledge about each modules' type (stored via
"ModuleType" enum). Module loading pipeline now stores information about
expected module type for each request and validates that expected type matches
discovered module type based on file's "MediaType".

Relevant tests were added to "core/modules.rs" and integration tests,
additionally multiple WPT tests were enabled.

There are still some rough edges in the implementation and not all WPT were
enabled, due to:
a) unclear BOM handling in source code by "FileFetcher"
b) design limitation of Deno's "FileFetcher" that doesn't download the same
module multiple times in a single run

feat(core): intercept unhandled promise rejections (#12910)
Provide a programmatic means of intercepting rejected promises without a
.catch() handler. Needed for Node compat mode.

Also do a first pass at uncaughtException support because they're
closely intertwined in Node. It's like that Frank Sinatra song:
you can't have one without the other.

Stepping stone for #7013.

feat(core): Add ability to "ref" and "unref" pending ops (#12889)
This commit adds an ability to "ref" or "unref" pending ops.

Up to this point Deno had a notion of "async ops" and "unref async ops";
the former keep event loop alive, while the latter do not block event loop
from finishing. It was not possible to change between op types after
dispatching, one had to decide which type to use before dispatch.

Instead of storing ops in two separate "FuturesUnordered" collections,
now ops are stored in a single collection, with supplemental "HashSet"
storing ids of promises that were "unrefed".

Two APIs were added to "Deno.core":

"Deno.core.refOp(promiseId)" which allows to mark promise id
to be "refed" and keep event loop alive (the default behavior)
"Deno.core.unrefOp(promiseId)" which allows to mark promise
id as "unrefed" which won't block event loop from exiting

feat(core): Deno.core.setNextTickCallback (#12771)
This commit adds several new "Deno.core" bindings:
* "setNextTickCallback"
* "hasScheduledTick"
* "setHasScheduledTick"
* "runMicrotasks"
Additionally it changes "Deno.core.setMacrotaskCallback" to
allow registering multiple callbacks. All these changes were necessary
to polyfill "process.nextTick" in Node compat layer.

refactor(core): Turn the wasm_streaming_feed binding into ops (#11985)
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.

feat: enable WebAssembly.instantiateStreaming and wasm async compilation (#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.

feat(inspector): pipe console messages between terminal and inspector (#11134)
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.

refactor(core): move ModuleMap to separate RefCell (#10656)
This commit moves bulk of the logic related to module loading
from "JsRuntime" to "ModuleMap".

Next steps are to rewrite the actual loading logic (represented by
"RecursiveModuleLoad") to be a part of "ModuleMap" as well --
that way we will be able to track multiple module loads from within
the map which should help me solve the problem of concurrent
loads (since all info about currently loading/loaded modules will
be contained in the ModuleMap, so we'll be able to know if actually
all required modules have been loaded).
