This patch adds a UnstrippedURI into the LoadInfo. This attribute
represents the channel's URI has been stripped if this attributes is not
a nullptr.
Having this attribute allows us to be able to revert the query stripping
in the case where the loading channel is in the content blocking allow
list in the parent process.
In addition, this patch removes the main thread assertion in URIUtils
given that we've made the URL construction thread-safe. This will allow
us to be able to use nsIURI directly in ParentLoadInfoForwarderArgs.
