feat: add Yarn PnP support

[merceyz]

What's the problem this PR addresses?

The tag providers can't be located under Yarn PnP due to hard coding node_modules

Fixes #2469

How did you fix it?

• Use require.resolve to locate tag providers
• Setup the PnP hook from the workspace if it exists

Would it be fine if I changed

vetur/server/src/services/dependencyService.ts

Line 165 in 03a4373

const packages = await findAllPackages(nodeModulesPaths, name);

to use require.resolve instead?
I guess that is supposed to half support workspaces, but at that point it should just run require.resolve in each workspace

I want to establish a dependency relationship in advance.
But I thought maybe in pnp it was redundant?

I'll omit that part for now

LGTM, I will merge when #2495 merged.
