OvmfPkg/Sec: Fix 64bit SEC build failure
...
Original code breaks a single assembly code to multiple lines.
But, when VS CL.exe preprocesses the FixedPcdGet32() macro
invocation to the replacement text, it loses '\', and causes
NASM to fail.
Changing the multiple lines to one line to resolve the build failure.

OvmfPkg/Sec/X64: seed the temporary RAM with PcdInitValueInTempStack
...
This allows the PEI core to report the maximum temporary SEC/PEI stack
usage on the DEBUG_INFO level, in the PeiCheckAndSwitchStack() function
[MdeModulePkg/Core/Pei/Dispatcher/Dispatcher.c]:
* Normal boot:
> Temp Stack : BaseAddress=0x814000 Length=0x4000
> Temp Heap : BaseAddress=0x810000 Length=0x4000
> Total temporary memory: 32768 bytes.
> temporary memory stack ever used: 5080 bytes. <----
> temporary memory heap used for HobList: 8080 bytes.
> temporary memory heap occupied by memory pages: 0 bytes.
* S3 resume (no SMM / PEI decompression)
> Temp Stack : BaseAddress=0x814000 Length=0x4000
> Temp Heap : BaseAddress=0x810000 Length=0x4000
> Total temporary memory: 32768 bytes.
> temporary memory stack ever used: 5048 bytes. <----
> temporary memory heap used for HobList: 7112 bytes.
> temporary memory heap occupied by memory pages: 0 bytes.
I unit-tested this change by transitorily adding an infinite loop right
after the "rep stosq", and dumping the guest's temp SEC/PEI RAM (32KB
currently) while the guest was stuck in the loop. The dump includes one
dword from before and after the temp SEC/PEI RAM:
> $ virsh qemu-monitor-command GUEST_NAME --hmp 'xp /8194wx 0x80FFFC'
>
> 000000000080fffc: 0x00000000 0x5aa55aa5 0x5aa55aa5 0x5aa55aa5
> 000000000081000c: 0x5aa55aa5 0x5aa55aa5 0x5aa55aa5 0x5aa55aa5
