Bug 1679325 - Part 1: Making contentAreaUtils.saveURL to accept cookieJarSettings. r=smaug

This patch makes the contentAreaUtils.saveURL to be aware of the
cookieJarSettings, and updates all callers.

This also updates the documentation of the persistArgs
'cookieJarSettings' for internalPersist().
