Adds, updates, or removes a configuration table entry from the System Management System Table.
The SmmInstallConfigurationTable() function is used to maintain the list
of configuration tables that are stored in the System Management System
Table. The list is stored as an array of (GUID, Pointer) pairs. The list
must be allocated from pool memory with PoolType set to EfiRuntimeServicesData.
@param[in] SystemTable A pointer to the SMM System Table (SMST).
@param[in] Guid A pointer to the GUID for the entry to add, update, or remove.
@param[in] Table A pointer to the buffer of the table to add.
@param[in] TableSize The size of the table to install.
@retval EFI_SUCCESS The (Guid, Table) pair was added, updated, or removed.
@retval EFI_INVALID_PARAMETER Guid is not valid.
@retval EFI_NOT_FOUND An attempt was made to delete a non-existent entry.
@retval EFI_OUT_OF_RESOURCES There is not enough memory available to complete the operation.
