Star Zeng 9aef515648 MdeModulePkg/DxeCore: Ensure FfsFileHeader 8 bytes aligned
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=864
REF: CVE-2018-3630

To follow PI spec, ensure FfsFileHeader 8 bytes aligned.

For the integrity of FV(especially non-MemoryMapped FV) layout,
let CachedFv point to FV beginning, but not (FV + FV header).

And current code only handles (FwVolHeader->ExtHeaderOffset != 0) path,
update code to also handle (FwVolHeader->ExtHeaderOffset == 0) path.
