msrtool: Factor out cpuid() from target probe functions into main()

Almost all probe functions called cpuid(). Those calls are replaced
by a single cpuid() call in main() and a new parameter to the target
probe functions with the cpuid() result.

The vendor_t and struct cpuid_t definitions are moved closer to the
top of msrtool.h and the vendor_t enum is reformatted to simplify
addition of further values.
