Implements a restricted subset of the WASI ABI (wasi_snapshot_preview1) to support proxy-wasm modules that require base level WASI functionality. This implementation adds a ABI_WASI class to handle WASI-specific functions: - Supports core WASI functions required by proxy-wasm spec - Implements fd_write for stdout/stderr logging - Adds support for clock, random, environment, and args functions This should result in a better sandboxing of the guest modules.
