0031737: Configuration - Add batch files to build OCCT with Emscripten

The scripts occ_build_wasm.bat and occ_build_wasm.sh have been added to simplify batch building of OCCT with Emscripten (Web Assembly packages) correspondingly on Windows and Linux platforms. These scripts are configurable through calling files with custom environment wasm_custom_env.bat and wasm_custom_env.sh.
