Make router and vuex proper packages

[pksunkara]

What problem does this feature solve?

There's a lot of careful manipulation being done in @vue/cli code because of the above plugins not being proper packages, which we could avoid. Since the implementation of #1202, the format of the above plugins is in a proper plugin format anyway. So, why don't we move them to their own packages in the repo? That way, we could remove all the specialty code written just for these packages.

What does the proposed API look like?

Have 2 new packages @vue/cli-plugin-router, @vue/cli-plugin-vuex

I'm reluctant to add two new generator-only plugins.
Even if we do, we should not mess up users' package.jsons; co-existence of @vue/cli-plugin-vuex and vuex would definitely confuse them.
So we'll still need to add some special logic to remove the plugins after generating the necessary files. Does that worth the refactoring?

I think yes, because right now the generation is not very consistent and also having these as internal options in cli-service generator is messing with other 3rd party plugins when they are doing this

co-existence of @vue/cli-plugin-vuex and vuex would definitely confuse them.

I actually have no issue about this as an end-user if the cli-plugin-vuex has more helpful commands (like maybe generating a store module etc..)

Yeah, definitely worth it if such features implemented.
It's been on my backlog for a while actually. Just haven't got the time to think about the design.

I will work on this and send a PR for the initial packages. Then we can discuss on the features to be implemented after that PR is merged. I am always up for a chat on discord if you need someone to brainstorm with.

😀Cool, much appreciated.
