Laszlo Ersek 509f8425b7 UefiCpuPkg: change PcdCpuSmmStackGuard default to TRUE 
This Feature PCD causes PiSmmCpuDxe to catch SMM stack overflow at
runtime, logging a clear error message, and entering a CPU dead loop.
Compared to the chaotic and catastrophic consequences of the stack leaking
into, and corrupting, the SMM page table, a stack guard that is enabled by
default is vastly superior.

We should not require sane platforms to explicitly opt in to this
safeguard; instead, we should require platforms that prefer to live
dangerously to opt out of it.

Stack overflow in SMM might even give rise to security vulnerabilities.
