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.

We are switching to ContinuationPreservedEmbedderData. This allows

perf(cli): use new deno_core timers (#22569)
Improves #19100 

Fixes #20356

Replaces #20428



Changes made in deno_core to support this:

 - [x] Errors must be handled in setTimeout callbacks
 - [x] Microtask ordering is not-quite-right
 - [x] Timer cancellation must be checked right before dispatch
 - [x] Timer sanitizer
 - [x] Move high-res timer to deno_core
 - [x] Timers need opcall tracing

chore(ext/web): refactor timer ops before landing op sanitizer (#22435)
Splitting the sleep and interval ops allows us to detect an interval
timer. We also remove the use of the `op_async_void_deferred` call.

A future PR will be able to split the op sanitizer messages for timers
and intervals.

chore: ensure that each op provided to ensureFastOps is only used once (#21689)
When we migrate to op-import-per-extension, we will want to ensure that
ops have one and only one place where they are imported. This tackles
the ops that are imported via `ensureFastOps`, but does not yet tackle
direct `ops` imports.

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.

perf: don't run microtask checkpoint if macrotask callback did no work (#19492)
Most of the time there's no firing timers, nor pending promise
rejections, so it's wasteful to run microtask checkpoint 
additionally twice on each tick of the event loop.

fix(ext/web): improve timers resolution for 0ms timeouts (#19212)
This commit changes the implementation of `ext/web` timers, by using
"op_void_async_deferred" for timeouts of 0ms.

0ms timeout is meant to be run at the end of the event loop tick and
currently Tokio timers that we use to back timeouts have at least 1ms
resolution. That means that 0ms timeout actually take >1ms. This
commit changes that and runs 0ms timeout at the end of the event
loop tick.

One consequence is that "unrefing" a 0ms timer will actually keep
the event loop alive (which I believe actually makes sense, the test
we had only worked because the timeout took more than 1ms).

refactor: migrate async ops to generated wrappers (#18937)
Migrates some of existing async ops to generated wrappers introduced in
https://github.com/denoland/deno/pull/18887. As a result "core.opAsync2"
was removed.

I will follow up with more PRs that migrate all the async ops to
generated wrappers.

perf(ext/websocket): use opAsync2 to avoid spread deopt (#18525)
This commit adds a new core API `opAsync2` to call an async op with
atmost 2 arguments. Spread argument iterators has a pretty big perf hit
when calling ops.

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.

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.

perf(ext/web): optimize timer cancellation (#16316)
Towards #16315 

It created a bunch of Error objects and rejected the promise. This patch
changes `op_sleep` to resolve with `true` if it was cancelled.

perf(ops): Monomorphic sync op calls (#15337)
Welcome to better optimised op calls! Currently opSync is called with parameters of every type and count. This most definitely makes the call megamorphic. Additionally, it seems that spread params leads to V8 not being able to optimise the calls quite as well (apparently Fast Calls cannot be used with spread params).

Monomorphising op calls should lead to some improved performance. Now that unwrapping of sync ops results is done on Rust side, this is pretty simple:

```
opSync("op_foo", param1, param2);
// -> turns to
ops.op_foo(param1, param2);
```

This means sync op calls are now just directly calling the native binding function. When V8 Fast API Calls are enabled, this will enable those to be called on the optimised path.

Monomorphising async ops likely requires using callbacks and is left as an exercise to the reader.
