IntelFsp2Pkg: Support Multi-Phase SiInit and debug handlers.

Browse Source 
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2698

To enhance FSP silicon initialization flexibility an optional
Multi-Phase API is introduced and FSP header needs update for
new API offset. Also new SecCore module created for
FspMultiPhaseSiInit API

New ARCH_UPD introduced for enhancing FSP debug message
flexibility now bootloader can pass its own debug handler
function pointer and FSP will call the function to handle
debug message.
To support calling bootloader functions, a FspGlobalData field
added to indicate if FSP needs to switch stack when FSP running
on separate stack from bootloader.
