tools: Add gzip-libdeflate advanced compressor Several devices provide U-Boot versions with only gzip compressed kernel support (e.g. Realtek switches). This compression method produces larger images than lzma. To save space on flash and avoid going the hard way with lzma-loader we can make use of enhanced gzip tool based on libdeflate compression library from https://github.com/ebiggers/libdeflate. It keeps 100% deflate/gzip compatibility while improving compression ratio. The image can be unpacked by the default inflate routines inside U-Boot.

tools: libdeflate: update to 1.20 Changes: * Improved CRC-32 performance on recent x86 CPUs by adding VPCLMULQDQ-accelerated implementations using 256-bit and 512-bit vectors. * Improved Adler-32 performance on recent x86 CPUs by adding VNNI-accelerated implementations using 256-bit and 512-bit vectors. * Improved CRC-32 and Adler-32 performance on short inputs. * Optimized the portable implementation of Adler-32. * Added some basic optimizations for RISC-V. * Dropped support for gcc versions older than v4.9 (released in 2014) and clang versions older than v3.9 (released in 2016). * Dropped support for CRC-32 acceleration on 32-bit ARM using the ARMv8 pmull or crc32 instructions. This code only worked on CPUs that also have a 64-bit mode, and it was already disabled on many compiler versions due to compiler limitations. CRC-32 acceleration remains fully supported on 64-bit ARM. Signed-off-by: Robert Marko <robimarko@gmail.com>

tools: libdeflate: fetch source as tarball libdeflate is currently intentionally being fetched via GIT. However, with the move to using ZSTD to compress the cloned GIT repo tarballs it means that we would first need to compile ZSTD. But that means that we need to be able to unpack gzipped tarballs first which we currently do by using libdeflate-gzip. So, in order to do so lets fetch libdeflate as a tarball, use gzip to extract it and then use libdeflate as regular for all other tools. Signed-off-by: Robert Marko <robimarko@gmail.com>
