Adding a new cmake flag (cache variable) `WAMR_BUILD_MEMORY64` to enable the memory64 feature, it can only be enabled on the 64-bit platform/target and can only use software boundary check. And when it is enabled, it can support both i32 and i64 linear memory types. The main modifications are: - wasm loader & mini-loader: loading and bytecode validating process - wasm runtime: memory instantiating process - classic-interpreter: wasm code executing process - Support memory64 memory in related runtime APIs - Modify main function type check when it's memory64 wasm file - Modify `wasm_runtime_invoke_native` and `wasm_runtime_invoke_native_raw` to handle registered native function pointer argument when memory64 is enabled - memory64 classic-interpreter spec test in `test_wamr.sh` and in CI Currently, it supports memory64 memory wasm file that uses core spec (including bulk memory proposal) opcodes and threads opcodes. ps. https://github.com/bytecodealliance/wasm-micro-runtime/issues/3091 https://github.com/bytecodealliance/wasm-micro-runtime/pull/3240 https://github.com/bytecodealliance/wasm-micro-runtime/pull/3260
