Update build scripts and documents of workload samples for wasi-sdk-12.0 (#484)

Browse Source 
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.

EMSDK is another toolchain to compile C/C++ code to WASM. In this case, the output wasm file
might have a higher performance than the file generated by wasi-sdk.
