udev: Extract RAM properties from DMI information

Add memory_id program to set properties about the physical memory
devices in the system. This is useful on machines with removable memory
modules to show how the machine can be upgraded, and on all devices to
detect the actual RAM size, without relying on the OS accessible amount.

Closes: #16651
