chore: deprecate Deno.Reader, Deno.ReaderSync, Deno.Writer, Deno.WriterSync and Deno.Closer (#21465)
This change deprecates `Deno.Reader`, `Deno.ReaderSync`, `Deno.Writer`,
`Deno.WriterSync` and `Deno.Closer` in favour of the [Web Streams
API](https://developer.mozilla.org/en-US/docs/Web/API/Streams_API).
After discussing with Yoshiya, we both thought now might be the right
time to deprecate these interfaces with v2 getting closer.

feat(ext/fetch): allow Deno.HttpClient to be declared with using (#21453)
This commit adds a method of `Symbol.dispose` to the object returned
from `Deno.createHttpClient`, so we can make use of [explicit resource
management](https://github.com/tc39/proposal-explicit-resource-management)
by declaring it with `using`.

feat(unstable): kv.watch() (#21147)
This commit adds support for a new `kv.watch()` method that allows

where you want to be notified when a key-value pair changes, but
don't want to have to poll for changes.

feat(ext/cron) modify Deno.cron API to make handler arg last (#21225)
This PR changes the `Deno.cron` API:
* Marks the existing function as deprecated
* Introduces 2 new overloads, where the handler arg is always last:
```ts
Deno.cron(
  name: string,
  schedule: string,
  handler: () => Promise<void> | void,
)

Deno.cron(
  name: string,
  schedule: string,
  options?: { backoffSchedule?: number[]; signal?: AbortSignal },
  handler: () => Promise<void> | void,
)
```

This PR also fixes a bug, when other crons continue execution after one
of the crons was closed using `signal`.

feat(cron) implement Deno.cron() (#21019)
This PR adds unstable `Deno.cron` API to trigger execution of cron jobs.

* State: All cron state is in memory. Cron jobs are scheduled according
to the cron schedule expression and the current time. No state is
persisted to disk.
* Time zone: Cron expressions specify time in UTC.
* Overlapping executions: not permitted. If the next scheduled execution
time occurs while the same cron job is still executing, the scheduled
execution is skipped.
* Retries: failed jobs are automatically retried until they succeed or
until retry threshold is reached. Retry policy can be optionally
specified using `options.backoffSchedule`.

feat(unstable): add Deno.jupyter.display API (#20819)
This brings in [`display`](https://github.com/rgbkrk/display.js) as part
of the `Deno.jupyter` namespace. 

Additionally these APIs were added:
- "Deno.jupyter.md"
- "Deno.jupyter.html"
- "Deno.jupyter.svg"
- "Deno.jupyter.format"

These APIs greatly extend capabilities of rendering output in Jupyter
notebooks.

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).

chore: deprecate Deno.metrics() API (#20684)
This API is providing hoops to jump through with undergoing migration to
`#[op2]` macro. 

The overhead of supporting this API is non-trivial and besides internal
use of it in test sanitizers is very rarely used in the wild.

fix(ext/http): create a graceful shutdown API (#20387)
This PR implements a graceful shutdown API for Deno.serve, allowing all
current connections to drain from the server before shutting down, while
preventing new connections from being started or new transactions on
existing connections from being created.

We split the cancellation handle into two parts: a listener handle, and
a connection handle. A graceful shutdown cancels the listener only,
while allowing the connections to drain. The connection handle aborts
all futures. If the listener handle is cancelled, we put the connections
into graceful shutdown mode, which disables keep-alive on http/1.1 and
uses http/2 mechanisms for http/2 connections.

In addition, we now guarantee that all connections are complete or
cancelled, and all resources are cleaned up when the server `finished`
promise resolves -- we use a Rust-side server refcount for this.

Performance impact: does not appear to affect basic serving performance
by more than 1% (~126k -> ~125k)

https://github.com/denoland/deno/actions/runs/5990043261/job/16246927846?pr=18642

The test is just `b.start(); b.end()` where the time measured between
must be less 10 μs during warmup. Can't improve it.

feat(unstable): Improve FFI types (#20215)
Few improvements to FFI types:
1. Export `PointerObject` for convenience. It's fairly commonly used in
library code and thus should be exported.
2. Fix various comments around `PointerValue` and `UnsafePointer` and
expand upon them to better reflect reality.
3. Instead of using a `Record<"value", type>[T]` for determining the
type of an FFI symbol parameter use direct `T extends "value" ? type :
never` comparison.

The last part enables smuggling extra information into the parameter and
return value string declarations at the type level. eg. Instead of just
`"u8"` the parameter can be `"u8" & { [brand]: T }` for some `T extends
number`. That `T` can then be extracted from the parameter to form the
TypeScript function's parameter or return value type. Essentially, this
enables type-safe FFI!

The foremost use-cases for this are enums and pointer safety. These are
implemented in the second commit which should enable, in a backwards
compatible way, for pointer parameters to declare what sort of pointer
they mean, functions to declare what the API definition of the native
function is, and for numbers to declare what Enum they stand for (if
any).

feat(permissions): add "--deny-*" flags (#19070)
This commit adds new "--deny-*" permission flags. These are complimentary to
"--allow-*" flags.

These flags can be used to restrict access to certain resources, even if they
were granted using "--allow-*" flags or the "--allow-all" ("-A") flag.

Eg. specifying "--allow-read --deny-read" will result in a permission error,
while "--allow-read --deny-read=/etc" will allow read access to all FS but the
"/etc" directory.

Runtime permissions APIs ("Deno.permissions") were adjusted as well, mainly
by adding, a new "PermissionStatus.partial" field. This field denotes that
while permission might be granted to requested resource, it's only partial (ie.
a "--deny-*" flag was specified that excludes some of the requested resources).
Eg. specifying "--allow-read=foo/ --deny-read=foo/bar" and then querying for
permissions like "Deno.permissions.query({ name: "read", path: "foo/" })"
will return "PermissionStatus { state: "granted", onchange: null, partial: true }",
denoting that some of the subpaths don't have read access.

Closes #18804.
