fix: class prototypes cannot be properly set

test_bytes_instanceof: Python bytes instanceof JS Uint8Array assert False

test_keys_iterator: TypeError iterator is not iterable

If `explicit-resource-management` is enabled, the lib .so will be compiled differently to the header files when there's a `IF_EXPLICIT_RESOURCE_MANAGEMENT` macro used.
The `enum JSProtoKey` index is off by 1 (header `JSProto_Uint8Array` 27 will be interpreted as `JSProto_Int8Array` in lib as lib has an extra element)
