OvmfPkg: set SMM stack size to 16KB
The default stack size (from UefiCpuPkg/UefiCpuPkg.dec) is 8KB, which
proved too small (i.e., led to stack overflow) across commit range
98c2d9610506^..f85d3ce2efc2^, during certificate enrollment into "db".
As the edk2 codebase progresses and OVMF keeps including features, the
stack demand constantly fluctuates; double the SMM stack size for good
measure.
