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.

<HelpText>The driver sets the NV Storage FV base address defined by this PCD.
This base address point to an EFI_FIRMWARE_VOLUMN_HEADER struct. Variable PEIM
will get the base address from this PCD. In NT emulator, this PCD is a DYNAMIC
type, as FD is mapped to process space by WinNT OS. On real platform, it is
normally a FIXED_AT_BUILD type as system memory map is fixed to BIOS.
