  REGRESSION(268342 at main): Web process crashes when loading a cross-origin WebM resource

Reviewed by Pascoe.

WebM video requests currently always set the first party for cookies to its own URL, so our
allowsFirstPartyForCookies message check will fail when loading a cross origin video. The resource
loader will end up setting the correct first party for cookies if one is not already set, so let’s
just not set one here.
