LibWeb: Fix mismatching Resource subclass types

Browse Source 
This was a confusing bug: ImageStyleValue loaded its image resource as
a Generic resource, while HTMLImageElement loaded as Image.

This patch fixes the issue and adds an assertion to verify that we only
share resources that have the same C++ client class type.
