* feat: use CDP's auto-attach mechanism
In this PR, we refactor Puppeteer to make use of the CDP's auto-attach mechanism. This allows the backend to pause
new targets and give Puppeteer a chance to configure them properly. This fixes the flakiness related to dealing with
OOPIFs and should fix some other issues related to the network interception and navigations. If those are not fixed completely by this PR, the PR serves a solid base for fixing them.
Closes https://github.com/puppeteer/puppeteer/issues/8507, https://github.com/puppeteer/puppeteer/issues/7990
Unlocks https://github.com/puppeteer/puppeteer/issues/3667
BREAKING CHANGE: With Chromium, Puppeteer will now attach to page/iframe targets immediately to allow reliable configuration of targets.
