feat: Start warning on each use of a deprecated API (#21939)
This commit introduces deprecation warnings for "Deno.*" APIs.

This is gonna be quite noisy, but should tremendously help with user
code updates to ensure
smooth migration to Deno 2.0. The warning is printed at each unique call
site to help quickly
identify where code needs to be adjusted. There's some stack frame
filtering going on to
remove frames that are not useful to the user and would only cause
confusion.

The warning can be silenced using "--quiet" flag or
"DENO_NO_DEPRECATION_WARNINGS" env var.

"Deno.run()" API is now using this warning. Other deprecated APIs will
start warning
in follow up PRs.

Example:

```js
import { runEcho as runEcho2 } from "http://localhost:4545/run/warn_on_deprecated_api/mod.ts";

const p = Deno.run({
  cmd: [
    Deno.execPath(),
    "eval",
    "console.log('hello world')",
  ],
});
await p.status();
p.close();

async function runEcho() {
  const p = Deno.run({
    cmd: [
      Deno.execPath(),
      "eval",
      "console.log('hello world')",
    ],
  });
  await p.status();
  p.close();
}

await runEcho();
await runEcho();

for (let i = 0; i < 10; i++) {
  await runEcho();
}

await runEcho2();

```

```

fix: strict type check for cross realms (#21669)
Deno v1.39 introduces `vm.runInNewContext`. This may cause problems when
using `Object.prototype.isPrototypeOf` to check built-in types.

```js
import vm from "node:vm";

const err = new Error();
const crossErr = vm.runInNewContext(`new Error()`);

console.assert( !(crossErr instanceof Error) );
console.assert( Object.getPrototypeOf(err) !== Object.getPrototypeOf(crossErr) );
```

This PR changes to check using internal slots solves them.

---

current: 

```
> import vm from "node:vm";
undefined
> vm.runInNewContext(`new Error("message")`)
Error {}
> vm.runInNewContext(`new Date("2018-12-10T02:26:59.002Z")`)
Date {}
```

this PR:

```
> import vm from "node:vm";

fix(unstable): Honor granular unstable flags in js runtime (#21466)
This fixes #21434 for `BroadcastChannel` and `WebSocketStream`.
`--unstable` still enable both, but granular unstable flags now also
work:

* `--unstable-net` now enables `WebSocketStream`.
* `--unstable-broadcast-channel` now enables `BroadcastChannel`.
* Additionally, there are now tests for all granular unstable flags.
Since `unsafe-proto` already had tests, so I didn't add any for this
one.

It also introduces a map to keep track of granular unstable ids without
having to sync multiple places.

chore: bump deno_core and update tests (#21467)
Landing changes required for
https://github.com/denoland/deno_core/pull/359

We needed to update 99_main.js and a whole load of tests.

API changes:

- setPromiseRejectCallback becomes setUnhandledPromiseRejectionHandler.
The function is now called from eventLoopTick.
- The promiseRejectMacrotaskCallback no longer exists, as this is
automatically handled in eventLoopTick.
- ops.op_dispatch_exception now takes a second parameter: in_promise.
The preferred way to call this op is now reportUnhandledException or
reportUnhandledPromiseRejection.

feat: granular --unstable-* flags (#20968)
This commit adds granular `--unstable-*` flags:
- "--unstable-broadcast-channel"
- "--unstable-ffi"
- "--unstable-fs"
- "--unstable-http"
- "--unstable-kv"
- "--unstable-net"
- "--unstable-worker-options"
- "--unstable-cron"

These flags are meant to replace a "catch-all" flag - "--unstable", that
gives a binary control whether unstable features are enabled or not. The
downside of this flag that allowing eg. Deno KV API also enables the FFI
API (though the latter is still gated with a permission).

These flags can also be specified in `deno.json` file under `unstable`
key.

Currently, "--unstable" flag works the same way - I will open a follow
up PR that will print a warning when using "--unstable" and suggest to use
concrete "--unstable-*" flag instead. We plan to phase out "--unstable"
completely in Deno 2.

This matches what browsers do:

In the future we might want to change the behavior to actually update
the process name, but that needs a bit of discussion regarding if
it needs a permission flag (that would make polyfiling `process.title`
setter really easy too).

feat(ext/node): eagerly bootstrap node (#20153)
To fix bugs around detection of when node emulation is required, we will
just eagerly initialize it. The improvements we make to reduce the
impact of the startup time:

 - [x] Process stdin/stdout/stderr are lazily created
 - [x] node.js global proxy no longer allocates on each access check
- [x] Process checks for `beforeExit` listeners before doing expensive
shutdown work
- [x] Process should avoid adding global event handlers until listeners
are added

fix: call setIsTrusted for generated events (MessageEvent) (#19919)
This addresses issue #19918.

## Issue description

Event messages have the wrong isTrusted value when they are not
triggered by user interaction, which differs from the browser. In
particular, all MessageEvents created by Deno have isTrusted set to
false, even though it should be true.

This is my first ever contribution to Deno, so I might be missing
something.

feat(ext/node): properly segregate node globals (#19307)
Code run within Deno-mode and Node-mode should have access to a
slightly different set of globals. Previously this was done through a
compile time code-transform for Node-mode, but this is not ideal and has
many edge cases, for example Node's globalThis having a different
identity than Deno's globalThis.

This commit makes the `globalThis` of the entire runtime a semi-proxy.
This proxy returns a different set of globals depending on the caller's
mode. This is not a full proxy, because it is shadowed by "real"
properties on globalThis. This is done to avoid the overhead of a full
proxy for all globalThis operations.

The globals between Deno-mode and Node-mode are now properly segregated.
This means that code running in Deno-mode will not have access to Node's
globals, and vice versa. Deleting a managed global in Deno-mode will
NOT delete the corresponding global in Node-mode, and vice versa.

This commit fixes emitting "unhandledrejection" event when there are
"node:" or "npm:" imports. 

Before this commit the Node "unhandledRejection" event was emitted
using a regular listener for Web "unhandledrejection" event. This
listener was installed before any user listener had a chance to be 
installed which effectively prevent emitting "unhandledrejection" 
events to user code.

refactor(runtime): manual serialization of bootstrap data (#18448)
This commit changes how data required to bootstrap main and worker
runtime is serialized. 

Instead of relying on serde_v8 and using JSON object,
we're doing manual serialization to a "v8::Array". This limits number 
of V8 strings that need to be serialized by 16. 

It also made it clear that some data could be obtained during
snapshotting instead of during bootstrap.

refactor: rename InternalModuleLoader to ExtModuleLoader, use ext: scheme for snapshotted modules (#18041)
This commit renames "deno_core::InternalModuleLoader" to
"ExtModuleLoader" and changes the specifiers used by the 
modules loaded from this loader to "ext:".

"internal:" scheme was really ambiguous and it's more characters than
"ext:", which should result in slightly smaller snapshot size.

Closes https://github.com/denoland/deno/issues/18020

perf: move runtime bootstrap code to snapshot time (#18062)
This commit moves some of the code from "99_main.js" to
be executed during the snapshot time instead of on each
worker bootstrap. These should minimally help with startup
time benchmark.
