Lets extend the 'struct MemoryRegion' to include ram_debug_ops callbacks. The ram_debug_ops can be used to override memcpy() with something else. The feature can be used by encrypted guest -- which can register callbacks to override memcpy() with memory encryption/decryption APIs. a typical usage: mem_read(uint8_t *dst, uint8_t *src, uint32_t len, MemTxAttrs *attrs);
