[PATCH v2] Platform/Intel: Dynamic NUMBER_OF_PROCESSORS in build.

["Chiu, Chasel" <chasel.chiu@intel.com>]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1913

To improve build performance by default the maximum
processors should be used for building.
NUMBER_OF_PROCESSORS in build.cfg is set to 0 so
BaseTools can utilize maximum processors for build.

Test: tried NUMBER_OF_PROCESSORS 0 and 1 cases and
      confirmed the build time is half with 0 case.
