This PR moves the puppeteer source code into separate mono-repo packages: - `puppeteer` and `puppeteer-core` are now separated into their own packages. - `puppeteer-core` has a new exports called `puppeteer-core/internal` for internal usage. Tests and various tools have been updated to accommodate the migration.
