dm vdo: add the compressed block bin packer
When blocks do not deduplicate, vdo will attempt to compress them. Up to 14
compressed blocks may be packed into a single data block (this limitation
is imposed by the block map). The packer implements a simple best-fit
packing algorithm and also manages the formatting and writing of compressed
blocks when bins fill.
