Bug 1612147 - Don't store FeaturePolicy in BrowsingContext. r=smaug

Browse Source 
Syncing the container FeaturePolicy across BrowsingContext is actually
a bit more heavy-handed than necessary. We only ever need a container
FeaturePolicy when inheriting a FeaturePolicy in exactly the document
the container contains. Not every process that the tree the container
is a part of. So instead of storing a FeaturePolicy in a synced field,
we manually send it to the correct WindowGlobalChild (which
corresponds to a document) and retrieve it from there.
