Subject: [PATCH] Added CPU utility function

Necessary for answering CPU of current machine when determining what
kind of functionality should be used when executing scripts on Silicon
or Intel based hardware. In this case, it'll answers "M1" when using an
Apple Silicon chip. For Intel based machines, nothing will be answered
since they use multiple "Processor" fields.
