Zhiguang Liu 14c9ba1a2c IntelFsp2Pkg: Support FSP API to save and restore page table 
A potential issue may happen when FSP creates/changes page table while
bootloader doesn't expect page table being changed in FSP.
Current, FSP API support to save/restore stack, IDT and general purpose
registers. Following the same pattern, add save/restore page table
support to solve this issue.
Note that this feature only impacts FSP API mode, and is controlled
by PCD PcdFspSaveRestorePageTableEnable. For compatibility, the PCD
default value is set as FALSE.
