fix(ext/node): lossy UTF-8 read node_modules files (#24140)

Previously various reads of files in `node_modules` would error on
invalid UTF-8. These were cases involving:

- reading package.json from Rust
- reading package.json from JS
- reading CommonJS files from JS
- reading CommonJS files from Rust (for ESM translation)
- reading ESM files from Rust
