fixes NEXT-479
## content
This PR adds a `getTracer` API to Next.js that uses the `otel/api` under
the hood to provide Next.js level instrumentation through Open
Telemetry.
This also adds an example `with-opentelemetry` to demonstrate how it can
be used, assuming you have a collector.
This allows most notably to have `getServerSideProps` and `fetch` calls
inside Server Components traced.
## details
- we hide most internals spans, if you want to see all of them, use the
NEXT_OTEL_VERBOSE=1 env var
- if you want to use this, you'll need to rely on the
`config.experimental.instrumentationHook` config option to initialise
OTEL, like in the example

This adds `loader-runner` to the compiled packages distributed with
Next.js
This is a dependency of Turbopack's webpack loader support. Currently,
users have to manually install `loader-runner` in their application to
use webpack loaders with Turbopack. This will allow Turbopack to require
loader-runner from within the installed version of Next.js instead.
Test Plan: `require('./packages/next/dist/compiled/loader-runner/')`

When you're trying to migrate an application from `pages/` to `app/`,
you'll need to access data like search parameters and the pathname in a
way that lets you migrate safely.
This adds support for dynamic typing of some of those exported functions
from `next/navigation`, namely `useSearchParams` and `usePathname`.
Currently, `searchParams` can’t be known when prerendering if the page
doesn’t use [Server-side
Rendering](https://nextjs.org/docs/basic-features/data-fetching/get-server-side-props)
in the `pages/` directory. `pathname` can’t be known during prerendering
if the page is a fallback page or has been automatically statically
optimized when accessed from `pages/`.
To make migraitons easier, this adds a new feature to `next dev` that
will automatically add the correct types for `next/navigation`. It does
this by checking if you have both a `app/` and `pages/` directory. If it
detects you have a `app/` directory, it will also enable the suggested
Typescript feature,
[`structNullChecks`](https://www.typescriptlang.org/tsconfig#strictNullChecks)
which will warn developers when trying to access a value that may be
`null`.

The PR upgrades `cross-spawn` to `7.0.3`. The precompiled has also been
updated. The `cross-spawn` version is still pinned after the PR.

So I have been working on improving Next.js build performance recently.
One thing that catches my eye is this:
<img width="1751" alt="image"
src="https://user-images.githubusercontent.com/40715044/218383194-5b24c737-0d97-4434-bbbf-ba5752072882.png">
The flamegraph shows the `semver` inside `cross-spawn` is one of the
hottest functions.
Then I take a look at the `cross-spawn`, turns out that `cross-spawn`
has `semver` already removed:
https://github.com/moxystudio/node-cross-spawn/pull/125
According to the CHANGELOG of `cross-spawn`, the only breaking change is
that `cross-spawn@7` is dropping `Node.js < 8` support. So I assume it
would be fine to upgrade `cross-spawn` to the latest version `7.0.3`,
thus eliminating the extra performance overhead introduced by `semver`.

- [x] Depends on https://github.com/vercel/next.js/pull/45776
Turbotrace occupies too many memories while running; this PR makes it
run after the webpack build is finished, it can reduce the memory
hogging by webpack and turbotrace, thus avoiding OOM
The `maxFiles` option in turbotrace is removed because there is
`memoryLimit` option takes over its role.
