wamr-compiler: add --llvm-version option (#4540) 
llvm is one of the most important component of wamrc.
otoh, i often forget which version of llvm i linked to my wamrc binary.
this option would help people with a dim memory like me.

```shell
spacetanuki% ./wamrc --llvm-version
LLVM 19.1.2
spacetanuki%
```

Build wamrc AOT compiler

Both wasm binary file and AOT file are supported by iwasm. The wamrc AOT compiler is to compile wasm binary file to AOT file which can also be run by iwasm. You can execute following commands to build wamrc compiler:

For Linux(Ubuntu 20.04 as an example):

First, make sure necessary dependency are installed:

sudo apt-get install git build-essential cmake g++-multilib libgcc-9-dev lib32gcc-9-dev ccache 

cd wamr-compiler
./build_llvm.sh (or "./build_llvm_xtensa.sh" to support xtensa target)
mkdir build && cd build
cmake .. (or "cmake .. -DWAMR_BUILD_PLATFORM=darwin" for MacOS)
make
# wamrc is generated under current directory

For Windows：

cd wamr-compiler
python build_llvm.py
mkdir build && cd build
cmake ..
cmake --build . --config Release
# wamrc.exe is generated under .\Release directory
