AOT call stack optimizations (#3773)
- Implement TINY / STANDARD frame modes - tiny mode is only able to keep track on the IP and func idx, STANDARD mode provides more capabilities (parameters, stack pointer etc.). - Implement FRAME_PER_FUNCTION / FRAME_PER_CALL modes - frame per function adds code at the beginning and at the end of each function for allocating / deallocating stack frame, whereas in per-call mode the frame is allocated before each call. The exception is call to the imported function, where frame-per-function mode also allocates the stack before the `call` instruction (as it can't instrument the imported function). At the moment TINY + FRAME_PER_FUNCTION is automatically enabled in case GC and perf profiling are disabled and `values` call stack feature is not requested. In all the other cases STANDARD + FRAME_PER_CALL is used. STANDARD + FRAME_PER_FUNCTION and TINY + FRAME_PER_CALL are currently not implemented but possible, and might be enabled in the future. ps. https://github.com/bytecodealliance/wasm-micro-runtime/issues/3758
