Closes #19399 (running without snapshots at all was suggested as an alternative solution). Adds a `__runtime_js_sources` pseudo-private feature to load extension JS sources at runtime for faster development, instead of building and loading snapshots or embedding sources in the binary. Will only work in a development environment obviously. Try running `cargo test --features __runtime_js_sources integration::node_unit_tests::os_test`. Then break some behaviour in `ext/node/polyfills/os.ts` e.g. make `function cpus() {}` return an empty array, and run it again. Fix and then run again. No more build time in between.
