fix(ext/node): throw ERR_UNKNOWN_BUILTIN_MODULE for unknown node: builtins (#34766)
Node's CommonJS loader throws `ERR_UNKNOWN_BUILTIN_MODULE` (with message
`No such built-in module: <id>`) when `require()` is given a
`node:`-prefixed specifier that is not a public builtin. Two cases were
handled incorrectly:
1. `require("node:unknown")` threw a generic `MODULE_NOT_FOUND` `Error`
instead of `ERR_UNKNOWN_BUILTIN_MODULE`.
2. `require("node:internal/...")` resolved to Deno's internal polyfill
modules. Node only exposes `internal/*` builtins under
`--expose-internals`, so from userland these should be treated as
unknown. This matches the existing `isBuiltin()` check and the public
`builtinModules` list, both of which already exclude `internal/*`.
This changes the `node:`-scheme branch of `Module._resolveFilename` to
skip `internal/*` ids and to throw
`internalErrors.ERR_UNKNOWN_BUILTIN_MODULE`. Bare (non-`node:`-prefixed)
`require("internal/...")` is intentionally left unchanged.
Enables the upstream test `parallel/test-require-node-prefix.js`.
