Evidence has shown that use of primordials have sometimes an impact of
performance. This commit reverts the changes who are most likely to be
responsible for performance regression in the HTTP response path.

I added a new custom ESLint rule to fix these problems.

We have a lot of replaceable codes with primordials.
Accessing built-in objects is restricted by existing rule
(no-restricted-globals), but accessing property in the built-in objects
is not restricted right now. We manually review codes that can be
replaced by primordials, but there's a lot of code that actually needs
to be fixed. We have often made pull requests to replace the primordials
with.

Restrict accessing global built-in objects such as `Promise`.
Restrict calling static methods such as `Array.from` or `Symbol.for`.
Don't restrict prototype methods to prevent false-positive.

typically by adding `.then(common.mustCall())` to verify that the

It's possible to annotate failures in Actions by printing
"::error file={},line={},col={}::{message}". This methos is preferrable
over using a problem matcher because problem matchers only allow
single-line messages, whereas ::error allows multi-line messages.

Currently, when a JS Http2Session object is created, we have
to handle the situation in which the native object corresponding
to it does not yet exist. As part of that, we create a typed array
for storing options that are passed through the `AliasedStruct`
mechanism, and up until now, we copied that typed array over
the native one once the native one was available.

This was not good, because it was overwriting the defaults that
were set during construction of the native typed array with zeroes.

In order to fix this, create a wrapper for the JS-created typed array
that keeps track of which fields were changed, which enables us to
only overwrite fields that were intentionally changed on the JS side.

It is surprising that this behavior was not tested (which is,
guessing from the commit history around these features, my fault).
The subseqeuent commit introduces a test that would fail without
this change.
