OvmfPkg/SmmCpuFeaturesLib: drop obsolete API implementation

Commit 0426115b6738 ("UefiCpuPkg: Remove unused API in
SmmCpuFeaturesLib.h", 2022-12-21) removed the declaration of the function
SmmCpuFeaturesAllocatePageTableMemory() from the "SmmCpuFeaturesLib.h"
library class header.

Remove the API's (null-)implementation from OvmfPkg/SmmCpuFeaturesLib as
well.

Testing: OVMF builds, boots, and suspends/resumes (see earlier in this
series).
