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:

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.
