Use MS-Windows system APIs to get number of processors
* lisp/emacs-lisp/comp.el: Use 'w32-get-nproc' instead of the
environment variable NUMBER_OF_PROCESSORS.
* src/w32proc.c (Fw32_get_nproc): New primitive.
* src/w32.c (w32_get_nproc): New function.
(sample_system_load): Call w32_get_nproc to initialize the number
of processors on this system.
* src/w32.h (w32_get_nproc): Add prototype.
