Map webRequest filter type to multiple internal ResourceTypes if needed

Map webRequest filter type to multiple internal ResourceTypes if needed

In the past, there was a 1-to-1 relation between content::ResourceType
and the public webRequest types. Since https://crbug.com/410382#c39
added multiple resource types that mapped to the same webRequest type,
this relation is no longer true (it's now a n-to-1 relation).

This change needs to be accounted for by registering multiple internal
filter types if a webRequest filter type is set that maps to more than
one content::ResourceType.
