v8.patch

# 1. Use already imported python dependencies
# 2. Disable pointer compression (limits the maximum number of WasmVMs).
# 3. Add support for --define=no_debug_info=1.
# 4. Allow compiling v8 on macOS 10.15 to 13.0. TODO(dio): Will remove this patch when https://bugs.chromium.org/p/v8/issues/detail?id=13428 is fixed.
# 5. Don't expose Wasm C API (only Wasm C++ API).
