refactor(tsc): rework based on first-party TS API

[johnsoncodehk]

• vue-tsc core code is re-implemented based on createProgram API
• Instead of additionally importing typescript, capture the typescript method from the tsc.js context:
  var ts = new Proxy({}, { get(_target, p, _receiver) {return eval(p); } } )
• Language-agnostic parts have been moved to @volar/typescript feat(typescript): add preset implementations volarjs/volar.js#108
• vue-tsc is consistent with the typescript plugin. It no longer distinguishes between .vue and .vue.ts file names. Instead, it uses the .vue file name uniformly, but provides the content of .vue.ts. This should resolve perf(tsc): support vue files with project reference delcaration #3751
• The tsc context is missing some typescript methods, and language-core needs to avoid using the missing methods:
  • node.forEachChild -> ts.forEachChild(node, ...
  • node.text -> sourceFile.text.substring(...)
  • sourceFile.getChildCount() -> ast.statements.length
  • node.getStart() -> ts.getTokenPosOfNode(node, sourceFile)
