test: update postmortem metadata test for V8 7.1

The V8 7.1 update requires the following adjustments to the
postmortem debugging metadata constants:

- v8dbg_class_JSArrayBuffer__byte_length__Object
  Use: v8dbg_class_JSArrayBuffer__byte_length__size_t

- v8dbg_class_JSArrayBufferView__raw_byte_length__Object
  Use: v8dbg_class_JSArrayBufferView__byte_length__size_t

- v8dbg_class_JSArrayBufferView__raw_byte_offset__Object
  Use: v8dbg_class_JSArrayBufferView__byte_offset__size_t

- v8dbg_class_String__length__SMI
  Use: v8dbg_class_String__length__int32_t
