fix: performance.timeOrigin (#26787)
`performance.timeOrigin` was being set from when JS started executing,
but `op_now` measures from an `std::time::Instant` stored in `OpState`,
which is created at a completely different time. This caused
`performance.timeOrigin` to be very incorrect. This PR corrects the
origin and also cleans up some of the timer code.

Compared to `Date.now()`, `performance`'s time origin is now
consistently within 5us (0.005ms) of system time.

perf(ext/web): optimize performance.measure() (#25774)
This PR optimizes the case when `performance.measure()` needs to find
the startMark by name. It is a simple change on `findMostRecent` fn to
avoiding copying and reversing the complete entries list.

Adds minor missing tests for:
- `clearMarks()`, general
- `clearMeasures()`, general
- `measure()`, case when the startMarks name exists more than once

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";

> vm.runInNewContext(`new Error("message")`)
Error: message

refactor: pull 'core', 'internals', 'primordials' from ES module (#21462)
This commit refactors how we access "core", "internals" and
"primordials" objects coming from `deno_core`, in our internal JavaScript code.

Instead of capturing them from "globalThis.__bootstrap" namespace, we
import them from recently added "ext:core/mod.js" file.

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

refactor: Use ES modules for internal runtime code (#17648)
This PR refactors all internal js files (except core) to be written as
ES modules.
`__bootstrap`has been mostly replaced with static imports in form in
`internal:[path to file from repo root]`.
To specify if files are ESM, an `esm` method has been added to
`Extension`, similar to the `js` method.
A new ModuleLoader called `InternalModuleLoader` has been added to
enable the loading of internal specifiers, which is used in all
situations except when a snapshot is only loaded, and not a new one is
created from it.
