Implement GC (Garbage Collection) feature for interpreter, AOT and LLVM-JIT (#3125)
Implement the GC (Garbage Collection) feature for interpreter mode, AOT mode and LLVM-JIT mode, and support most features of the latest spec proposal, and also enable the stringref feature. Use `cmake -DWAMR_BUILD_GC=1/0` to enable/disable the feature, and `wamrc --enable-gc` to generate the AOT file with GC supported. And update the AOT file version from 2 to 3 since there are many AOT ABI breaks, including the changes of AOT file format, the changes of AOT module/memory instance layouts, the AOT runtime APIs for the AOT code to invoke and so on.
