mm: split out sparse declarations from internal.h mm/internal.h becomes more and more bloated. Move declarations related to SPARSE and SPARSE_VMEMMAP memory models to a new mm/sparse.h header. No functional changes.

mm/sparse: keep mem_section_usage_size() internal mem_section_usage_size() is only needed by sparsemem implementation code after commit ae751d567baa ("mm/bootmem_info: stop marking mem_section_usage as MIX_SECTION_INFO"), so keeping the declaration in mmzone.h now exposes the helper to all mmzone.h users for no reason. Move the helper to sparse.h so sparse.c and sparse-vmemmap.c can share it through the internal header. While doing so, calculate the allocation size with struct_size_t(), which ties the expression to the pageblock_flags trailing array instead of open-coding the struct header plus bitmap size.
