as high-level API on top of `llvm::compression::{zlib,zstd}::*`.

Move `llvm::DebugCompressionType` from MC to Support. There are 40+ uses in
llvm-project. I am considering renaming it to `llvm::CompressionFormat` (or
possibly under llvm::compression).

See D130458 <https://reviews.llvm.org/D130458> (llvm-objcopy --{,de}compress-debug-sections for zstd) for a use
case.
