Update build scripts and documents of workload samples for wasi-sdk-12.0 (#484) 
Update the build scripts of sample workloads (meshoptimizer/bwa/wasm-av1) to use the wasi-sdk-12.0 firstly to build the workload and discard clang-11, as wasi-sdk-12 supports wasi, simd and pthread better. And update the related documents.
Also modify wasm mini loader to sync up with the change of wasm normal loader.

"XNNPACK" sample introduction

This sample demonstrates how to build XNNPACK benchmarks into WebAssembly with emsdk toolchain and run them with iwasm.

Installation toolchains

cd /opt
git clone https://github.com/emscripten-core/emsdk.git
cd emsdk
./emsdk install latest
./emsdk activate latest

And set up ensdk environment:

source /opt/emsdk/emsdk_env.sh

Build XNNPACK

cd <wamr-dir>/samples/workload/XNNPACK
mkdir build
cd build
cmake ..

The wasm files are generated under folder samples/workload/XNNPACK/xnnpack/bazel-bin.

Run benchmarks

Firstly please build iwasm with simd, libc-emcc and lib-pthread support:

$ cd <wamr-dir>/product-mini/platforms/linux/
$ mkdir build && cd build
$ cmake .. -DWAMR_BUILD_SIMD=1 -DWAMR_BUILD_LIBC_EMCC=1 -DWAMR_BUILD_LIB_PTHREAD=1
$ make

And please build wamrc:

cd <wamr-dir>/wamr-compiler
./build_llvm.sh
mkdir build && cd build
cmake ..
make

Then compile wasm file to aot file and run:

$ cd <wamr-dir>/samples/workload/XNNPACK/xnnpack/bazel-bin
$ wamrc --enable-simd -o average_pooling_bench.aot average_pooling_bench.wasm  (or other wasm files)
$ iwasm average_pooling_bench.aot
