Document how to use WASI threads in AOT mode (#1905) 
Describe how to use WASI threads in AOT mode, following the discussion below:
  https://github.com/bytecodealliance/wasm-micro-runtime/pull/1867#discussion_r1070268062

Make aux stack boundary checks of wasi-threads always successful by setting
`exec_env->aux_stack_bottom` to UINT32_MAX and `exec_env->aux_stack_boundary` to 0

"WASI threads" sample introduction

Currently, since the wasi-sdk does not have thread support in the latest release, make sure to have wasi-libc installed. Build it with threads enabled, e.g.

make \
    AR=/opt/wasi-sdk/bin/llvm-ar \
    NM=/opt/wasi-sdk/bin/llvm-nm \
    CC=/opt/wasi-sdk/bin/clang \
    THREAD_MODEL=posix

Build and run the samples

$ mkdir build
$ cd build
$ cmake -DWASI_SYSROOT=/path/to/wasi-libc/sysroot ..
$ make
...
$ ./iwasm wasm-apps/no_pthread.wasm
...
$ ./iwasm wasm-apps/exception_propagation.wasm

Run samples in AOT mode

$ ../../../wamr-compiler/build/wamrc \
    -o wasm-apps/no_pthread.aot wasm-apps/no_pthread.wasm
$ ./iwasm wasm-apps/no_pthread.aot
