vue: Install a global version of TypeScript if not present in the project (#14747)

This PR updates the Vue extension with support for installing and using
its own copy of TypeScript if it can't find one in the project.

The way we resolve `typescript` is as follows:

- We check the project's `package.json` for `typescript` in either the
`devDependencies` or `dependencies`
- If found, we set the `typescript.tsdk` to
`node_modules/typescript/lib` to use the project's copy of TypeScript
- If not found, we install the latest version of `typescript` (if not
already downloaded) to the extension's `package.json` and use that
version for `typescript.tsdk`

This should resolve instances where Vue projects that do not have an
explicit `typescript` dependency—such as those using Vue with plain
JavaScript—fail to load the language server due to TypeScript not being
found.

Release Notes:

- N/A
```
