mm/truncate: Split invalidate_inode_page() into mapping_evict_folio()
Some of the callers already have the address_space and can avoid calling
folio_mapping() and checking if the folio was already truncated. Also
add kernel-doc and fix the return type (in case we ever support folios
larger than 4TB).
