Switch to static zstd library and update build config

Replaces dynamic libzstd.1.dylib with static libzstd.a in CMakeLists.txt and updates architecture to support arm64. Adds zstd headers and static library, updates documentation and credits to reflect zstd usage, and removes unused tinyhook source files after moving headers and libraries.
