Subject: [PATCH] MdeModulePkg/StatusCodeHandlerRuntimeDxe: make global
 variable static

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'.
