esm: use "node:" internal namespace for builtins #35387

This has been discussed a couple of times in the past few meetings that the internal representation for builtins should align with policies using the node: scheme as well as to allow this to be the scheme to make public for users in future if we ever want to expose it more explicitly in any modules APIs or interfaces.

This is strictly a minor breaking change, but should have relatively low usage in the wild and is entirely limited to the experimental modules and loader cases.

To be very explicit, this breaks any code which imports nodejs:xyz.

The likelihood that there's lots of code that uses a protocol whatsoever is vanishingly small; it seems like a good idea to get this change into v15.

Maybe we could use primordials here?

Which added support for named exports for CJS via static analysis:
nodejs/node#35249
nodejs/node@1e8cb08edc for v15
nodejs/node@f551f52f83 for v14.13
nodejs/node@9eb1fa1924 for v12.20

This is also necessary for `node:` scheme support, checked by the
`unicorn/prefer-node-protocol` ESLint rule (currently disabled pending
support in eslint-plugin-node):
nodejs/node#35387
nodejs/node@ee9e3e75aa for v15
nodejs/node@91b820e939 for v14.13.1

Support for the 'node:' prefixed builtin module namespace was introduced
for `require()` expressions in Node v16.0.0, and backported to v14.18.0.
This was never supported in Node v15.x or chronologically older.

All of the current API history notes in the docs using 'node:' prefixed
module `require()`s happen to be documenting changes in Node versions
from before the time when support was first introduced.

This commit reverts those `require()`s in the history notes to be
un-prefixed. (They were incorrect as written; The prefixed `require()`s
would not work for those older Node versions.)

This change prevents the API history notes from inaccurately implying
'node:' prefixed builtin modules were introduced many Node versions ago,
or were `require()`-able with the 'node:' prefix in those Node versions.
