Export a lightweight headless tokenscript engine

[JustinFeng]

Changes include

• extract interface of ITokenScriptEngine, ITokenScript
• make the references in tokenscript sub modules depending on the interface (most of the changes is related to this, as the type is now set to the interface rather than the implementation)
• implemented LiteTokenScriptEngine and LiteTokenScript with dependencies trimmed for headless usage in token-kit and other non-ui scenarios

examples

// create tokenscript object
const tokenscript: LiteTokenScript = await liteTsEngine.getTokenScriptFromUrl(scriptURI);
tokenscript.setCurrentTokenContext(
    Object.keys(tokenscript.getOrigins())[context.originIndex],
    null,
    context.tokenId,
);

// read info from the tokenscript object
await tokenscript.getSecurityInfo().getInfo()
