498906f2 - [BOLT] Error out on SHF_COMPRESSED debug sections (#185662)

[BOLT] Error out on SHF_COMPRESSED debug sections (#185662) Some binaries are built using `-gz=zstd`, but when using `--update-debug-sections` on said binaries BOLT crashes. This patch fixes this issue by recognising compressed debug sections in binaries via their flag `SHF_COMPRESSED` and appropriately erroring out. Legacy GNU-style compression is not handled.
