fix: vitest tsconfig should include all files under src

Fixes vuejs#55

Fixes the case that a `.spec.ts` file inside `__test__/` imports a
module outside of `__test__/` (a cross-(typescript-)project reference).

Note that TypeScript looks for `include` patterns in `references`
top-down, so `tsconfig.app.json` must come before `tsconfig.vitest.json`
so that the `src/**` modules can get the most-accurate type hints.

The previous tsconfig only works for `.vue` imports in `.spec.ts`, which
seems to be a Volar bug. We shouldn't rely on that.
This fix is a more accurate configuration.
