qwang12 dd70a8c4e6 Variable PEIM use to PCD entry to get the base address of NV Storegae region.
This patch changes:

1) make the PcdFlashNvStorageVariableBase PCD entry type in Variable PEIM to be "DYNAMIC", which means it can be flexible to be FIX_AT_BUILD, DYNAMIC or PATCH_IN_MODULE.
2) make FlashMap depends on PCD_PPI
3) make FlashMap PEIM to the value of PcdFlashNvStorageVariableBase according NT emulator's FwhPPI installed by NT32 emulator's SEC.
