[PATCH] Platform/Intel: Add fspapi build parameter

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

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1824

Going forward FSP Dispatch mode will be default in
KabylakeOpenBoardPkg and requires fspapi build parameter
to switch back to FSP API mode.
When --fspapi given to build python script it will set
gIntelFsp2WrapperTokenSpaceGuid.PcdFspModeSelection to
1, otherwise the PCD will be the default value defined
by each *BoardPkg.

Test: verified the PCD PcdFspModeSelection can be
      overridden by new build parameter.
