Publish an extension to the visual studio marketplace using a secret token.
This allows for automation to take place because downloading and installing
the extension is a manual process so it'd be simpler if the extension was
published automatically through the visual studio marketplace.
Add CIs to enable the release process of a new version of WAMR,
and build and publish the binary files when a version is released,
including iwasm, wamrc, lldb, vscode-extension and wamr-ide for
Ubuntu-20.04, Ubuntu-22.04 and MacOS.
And refine the CIs to test spec cases.
