Target: 42-x-y

Backport of #53115

See that PR for details. Same adjustments as the 43-x-y backport (plain new for the self-deleting factories), plus context conflicts in electron_api_web_contents.cc, electron_api_web_contents.h and electron_browser_context.h (GetURLLoaderFactory is not an override here).

Notes: Page resources, fetch() calls and file:// loads in renderers no longer wait for the main process to be idle when no webRequest listeners or protocol interceptors are registered.
