// Creates a URLLoaderFactory that should be used for requests initiated from
// `process` by `origin`.
//
// The behavior of this method depends on the intended consumer of the
// URLLoaderFactory:
// - "web": No changes are made to `factory_params` - an extensions-agnostic,
// default URLLoaderFactory should be used
// - "extension": Extension-specific permissions are set in `factory_params`
// if the factory will be used by an extension frame (e.g. from an extension
// background page).
// - "content script": For most extensions no changes are made to
// `factory_params`, but platform apps might need to set app-specific
// security properties in the URLLoaderFactory used by content scripts.
// The method recognizes the intended consumer based on `origin` ("web" vs
// other cases) and `is_for_isolated_world` ("extension" vs "content script").
//
// The following examples might help understand the difference between
// `origin` and other properties of a factory and/or network request:
//
// | web | extension | content script
// --------------------------------|-----------|-------------|---------------
// network::ResourceRequest: | | |
// - request_initiator | web | extension | web
// - isolated_world_origin | nullopt | nullopt | extension
// | | |
// OverrideFactory...Params: | | |
// - origin | web | extension | extension
// | | |
// URLLoaderFactoryParams: | | |
// - request_initiator_origin_lock | web | extension | web
// - overridden properties? | no | yes | if needed
// - is_orb_enabled | secure- | ext-based | ext-based for
