ntfs: add non-resident WOF decompression

Browse source 
Introduce non-resident Windows System Compression (WOF) decompression
support. Add wof.c containing parse_wof_chunk_table() and
ntfs_read_wof_compressed_block(), and routing them via transparent
codec ops table with dynamic scratch memory allocation. Hook up
ntfs_readpage/read_folio paths in aops.c to delegate to the WOF block
reader when NInoWofCompressed is set.
