Implement WAMR-IDE with vscode extension (#943)

Implement WAMR-IDE with vscode extension to enable developing
WebAssembly applications with coding, building, running and
debugging support. Support both Linux and Windows, and only
support putting all the tools in a docker image, e.g. wasi-sdk, wamrc,
iwasm and so on.
