Forward apis

[alinpahontu2912]

Fixes #1550

Follow TarReader implementation to create forward only apis for streaming Zip entries, without having to load the whole archive in memory. This enables reading Zip entries from network streams, pipes, and stdi

Pull request overview

Adds a forward-only ZIP reading API to System.IO.Compression, enabling sequential entry access from non-seekable streams (network/pipes) without loading the full archive.

Changes:

• Introduces new public types ZipStreamReader and ZipForwardReadEntry for streaming ZIP entry enumeration and extraction.
• Adds unit tests covering forward-only reading scenarios (known sizes, data descriptors, copy-data behavior, cancellation, etc.).
• Updates supporting infrastructure (custom streams, resources, ref surface, and project files) to wire in the new API.
