Target: 44-x-y

Backport of #53115

See that PR for details. Only a member-list context conflict in electron_api_web_contents.h (44-x-y lacks the caret-browsing refcount); resolved by hand.

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.
