Add an optional length header attribute to the device tree blob entry class based on the compressed data header from the utilities to compress and decompress data.
If needed the header could be enabled with the following attribute beside the compress attribute: prepend = "length";
The header was introduced as part of commit eb0f4a4cb402 ("binman: Support replacing data in a cbfs") to allow device tree entries to be larger than the compressed contents. Regarding the commit "this is necessary to cope with a compressed device tree being updated in such a way that it shrinks after the entry size is already set (an obscure case)". This case need to be fixed without influence any compressed data by itself.

(no changes since v3)
This looks fine except that it drops test coverage (binman test -T should be 100%). Please can you check it?
