Summary:
In follow-up to https://github.com/facebook/rocksdb/issues/14315
Remove obsolete code replaced by new Compressor/Decompressor interface:
* OLD_CompressData and OLD_UncompressData
* Individual compression/decompression functions (Snappy_*, Zlib_*, BZip2_*, LZ4_*, LZ4HC_*, XPRESS_*, ZSTD_Compress, ZSTD_Uncompress)
* CompressionInfo and UncompressionInfo classes
* UncompressionDict class
* compression::PutDecompressedSizeInfo and GetDecompressedSizeInfo
The only small refactoring in this change that is not pure code removal or movement is in blob_file_builder_test.cc.
Move some function implementations etc. from compression.h to compression.cc:
* CompressionTypeToString, CompressionTypeFromString, CompressionOptionsToString
* ZSTD_TrainDictionary (both overloads), ZSTD_FinalizeDictionary
* DecompressorDict::Populate
* Most compression library includes
Also cleaned up other includes of compression.h, which caused some other files to need new includes.
