OvmfPkg/SmmCpuFeaturesLib: drop obsolete API implementation

Browse Source 
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.
