Changyu Bi c2aad555c3 Add `CompressionOptions::checksum` for enabling ZSTD checksum (#11666)
Summary:
Optionally enable zstd checksum flag (d857369028/lib/zstd.h (L428)) to detect corruption during decompression. Main changes are in compression.h:
* User can set CompressionOptions::checksum to true to enable this feature.
* We enable this feature in ZSTD by setting the checksum flag in ZSTD compression context: `ZSTD_CCtx`.
* Uses `ZSTD_compress2()` to do compression since it supports frame parameter like the checksum flag. Compression level is also set in compression context as a flag.
* Error handling during decompression to propagate error message from ZSTD.
* Updated microbench to test read performance impact.

About compatibility, the current compression decoders should continue to work with the data created by the new compression API `ZSTD_compress2()`: https://github.com/facebook/zstd/issues/3711.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/11666

Test Plan:
* Existing unit tests for zstd compression
* Add unit test `DBTest2.ZSTDChecksum` to test the corruption case
* Manually tested that compression levels, parallel compression, dictionary compression, index compression all work with the new ZSTD_compress2() API.
* Manually tested with `sst_dump --command=recompress` that different compression levels and dictionary compression settings all work.
* Manually tested compiling with older versions of ZSTD: v1.3.8, v1.1.0, v0.6.2.
* Perf impact: from public benchmark data: http://fastcompression.blogspot.com/2019/03/presenting-xxh3.html for checksum and https://github.com/facebook/zstd#benchmarks, if decompression is 1700MB/s and checksum computation is 70000MB/s, checksum computation is an additional ~2.4% time for decompression. Compression is slower and checksumming should be less noticeable.
* Microbench:
