LibCore: Store ObjectRegistration names as StringViews

Browse source 
We don't need to be allocating Strings for these names during static
initialization. The C-string literals will be stored in the .rodata ELF
section, so they're not going anywhere. We can just wrap the .rodata
storage for the class names in StringViews and use those in Object
registration and lookup APIs.
