perf(ext/node): convert net, _tls_common, _tls_wrap to lazy-loaded JS

[bartlomieju]

Follow-up to #33988. Moves the node:_tls_common, node:_tls_wrap, and
node:net polyfills off the eager-evaluated ESM path by rewriting their
sources as IIFEs registered under lazy_loaded_js, with thin
_esm.ts/_esm.js wrappers in lazy_loaded_esm re-exporting the named
members.

net.ts reads Duplex from node:stream and ADDRCONFIG/lookup
from node:dns at module top level, so net_esm.ts adds side-effect
imports of both — without them, the lazy createLazyLoader calls hit a
not-yet-loaded module when _http_agent.js pulls node:net very early
during 01_require.js instantiation. For the same reason
internal/tty.js's top-level ObjectSetPrototypeOf(WriteStream..., lazyNet().Socket.prototype) is deferred into an
ensureWriteStreamPrototype() helper called from the WriteStream
constructor, so it never reaches into net_esm.ts's Socket export
while that wrapper is still mid-evaluation. _readline.mjs and
node:readline = readline.ts also relocate from esm to
lazy_loaded_esm without IIFE conversion, since repl.ts still
statically imports _readline.mjs. The node:repl conversion is left
for a follow-up: repl.ts reads Module, process, Console, etc.
at module top level, and the only IIFE-compatible workaround is a
Proxy-based deferred accessor that I'd rather not introduce.
