REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3564

This function has not been called since it was added in commit
9bedaec. If the function were to remain, it would need to be
re-evaluated and tested. This change removes the function since
it is not being used.

-  Migrates SEC modules in the given firmware volume.

-  Migrating SECURITY_CORE files requires special treatment since they are not tracked for PEI dispatch.

-  This functioun should be called after the FV has been copied to its post-memory location and the PEI Core FV list has
-  been updated.
-
-  @param Private          Pointer to the PeiCore's private data structure.
-  @param FvIndex          The firmware volume index to migrate.
-  @param OrgFvHandle      The handle to the firmware volume in temporary memory.
-
-  @retval   EFI_SUCCESS           SEC modules were migrated successfully
-  @retval   EFI_INVALID_PARAMETER The Private pointer is NULL or FvCount is invalid.
-  @retval   EFI_NOT_FOUND         Can't find valid FFS header.
