[PATCH V2 6/8] IntelFsp2WrapperPkg/FspWrapperNotifyDxe: Decrease the name collisions

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

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

Add a 'static' descriptor to the global variables that only
used in a single file to minimize the name collisions.
This is only for the varable named 'mExitBootServicesEvent'.
