Automate WASM build with a new Python script. The script provides
several build profiles with configure flags for Emscripten flavors
and WASI. The script can detect and use Emscripten SDK and WASI SDK from
default locations or env vars.
``configure`` now detects Node arguments and creates HOSTRUNNER
arguments for Node 16. It also sets correct arguments for
``wasm64-emscripten``.
wasi-env now sets WASIX flags. This allows us to control all build
parameter for wasm32-wasi buildbot from CPython repository.
Also export and improve SYSROOT parameter.
