zstd excels at scaling from low-ratio-very-fast to high-ratio-pretty-slow. Some users prioritize speed and prefer disk read speed, while others focus on achieving the highest compression ratio possible, similar to traditional high-ratio codecs like LZMA. Add an optional `level` to `--compress-sections` (#84855) to cater to these diverse needs. While we initially aimed for a one-size-fits-all approach, this no longer seems to work. (https://richg42.blogspot.com/2015/11/the-lossless-decompression-pareto.html) When --compress-debug-sections is used together, make --compress-sections take precedence since --compress-sections is usually more specific. Remove the level distinction between -O/-O1 and -O2 for --compress-debug-sections=zlib for a more consistent user experience. Pull Request: https://github.com/llvm/llvm-project/pull/90567
