Give all different kFilteredMessages unique prefixes

There are 5 different kFilteredMessages arrays in content/browser
and some of them collide in jumbo (chromium unity builds)
build experiments.

This patch renames them to:
kCacheFilteredMessageClasses
kFileApiFilteredMessageClasses
kPepperFilteredMessageClasses
kRenderFilteredMessageClasses
kServiceWorkerFilteredMessageClasses
