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).

-/**
- This API provides a method for a CPU to allocate a specific region for
- storing page tables.
-
- This API can be called more once to allocate memory for page tables.
-
- Allocates the number of 4KB pages of type EfiRuntimeServicesData and returns
- a pointer to the allocated buffer. The buffer returned is aligned on a 4KB
- boundary. If Pages is 0, then NULL is returned. If there is not enough
- memory remaining to satisfy the request, then NULL is returned.
-
- This function can also return NULL if there is no preference on where the
- page tables are allocated in SMRAM.
-
- @param Pages The number of 4 KB pages to allocate.
-
- @return A pointer to the allocated buffer for page tables.
- @retval NULL Fail to allocate a specific region for storing page tables,
- Or there is no preference on where the page tables are
- allocated in SMRAM.
