MdeModulePkg PcdDxe: ASSERT PcdSetNvStoreDefaultId set 

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1245

In current implementation and according to the description in
MdeModulePkg.dec, PcdSetNvStoreDefaultId should be set in PEI
phase to take effect.

This patch ASSERTs PcdSetNvStoreDefaultId set in PcdDxe to alert
the invalid operation.
