Subject: [PATCH] Remove std.zip.Decompress (unused/broken/obsolete)

This API is unused, doesn't compile, and is a holdover from the previous std.zip implementation where the analogous functionality was in a decompress() function that was used within Entry.extract. The decompression functionality is now inlined in Entry.extract so this Decompress struct is superfluous.

Closes #35678
