UefiCpuPkg/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 UefiCpuPkg/SmmCpuFeaturesLib
as well.
Build-tested with:
build -a IA32 -a X64 -b NOOPT -p UefiCpuPkg/UefiCpuPkg.dsc -t GCC5

-/**
- 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.
