This patch introduces a DecompressionStreamAlgorithms abstract base class, which is implemented by ZLibDecompressionStreamAlgorithms and ZstdDecompressionStreamAlgorithms. It also introduces a new static pref for the "zstd" format to be used with CompressionStream and DecompressionStream, and introduces new WPTs for zstd DecompressionStream with equivalent coverage to those for ZLib.
