[PATCH V3 6/8] IntelFsp2WrapperPkg/FspWrapperNotifyDxe: make global variable static

["Gao, Zhichao" <zhichao.gao@intel.com>]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1740

Add a 'static' storage-class specifier to the global variables
that only used in a single file to minimize the name collisions.
This is only for the variable named 'mExitBootServicesEvent'.
