refactor: use v8 serialization for ipc (#20214)
* refactor: use v8 serialization for ipc * cloning process.env doesn't work * serialize host objects by enumerating key/values * new serialization can handle NaN, Infinity, and undefined correctly * can't allocate v8 objects during GC * backport microtasks fix * fix compile * fix node_stream_loader reentrancy * update subframe spec to expect undefined instead of null * write undefined instead of crashing when serializing host objects * fix webview spec * fix download spec * buffers are transformed into uint8arrays * can't serialize promises * fix chrome.i18n.getMessage * fix devtools tests * fix zoom test * fix debug build * fix lint * update ipcRenderer tests * fix printToPDF test * update patch * remove accidentally re-added remote-side spec * wip * don't attempt to serialize host objects * jump through different hoops to set options.webContents sometimes * whoops * fix lint * clean up error-handling logic * fix memory leak * fix lint * convert host objects using old base::Value serialization * fix lint more * fall back to base::Value-based serialization * remove commented-out code * add docs to breaking-changes.md * Update breaking-changes.md * update ipcRenderer and WebContents docs * lint * use named values for format tag * save a memcpy for ~30% speedup * get rid of calls to ShallowClone * extra debugging for paranoia * d'oh, use the correct named tags * apparently msstl doesn't like this DCHECK * funny story about that DCHECK * disable remote-related functions when enable_remote_module = false * nits * use EnableIf to disable remote methods in mojom * fix include * review comments
