LibWeb+Meta: Add wrapper for the BufferSource/ArrayBufferView IDL types

Browse source 
These wrappers will make it much easier to do various operations on the
different ArrayBuffer-related classes in LibWeb compared to the current
solution, which is to just accept a Handle<Object> everywhere (and use
"any" in the *.idl files).
