Add new tests io_read_d[1234] in t_ptrace_wait{,3,4,6,id,pid}
io_read_d1:
Verify PT_IO with PIOD_READ_D and len = sizeof(uint8_t)
io_read_d2:
Verify PT_IO with PIOD_READ_D and len = sizeof(uint16_t)
io_read_d3:
Verify PT_IO with PIOD_READ_D and len = sizeof(uint32_t)
io_read_d4:
Verify PT_IO with PIOD_READ_D and len = sizeof(uint64_t)
