libext2fs: add EXT2_FLAG_SHARE_DUP to de-duplicate data blocks When assigning physical address for new data block, search sha of existing blocks for match. If there's a match, reuse address of the matched block. Also set EXT4_FEATURE_RO_COMPAT_SHARED_BLOCKS in de-duped image. Bug: 64109868 Change-Id: I8d2d22e9c301264413c1454c84d7bf6bb32ac5c0
