Add $ vike dev and $ vike build

[brillout]

Description

- $ vite dev
+ $ vike dev

- $ vite build
+ $ vike build

Back in the vite-plugin-ssr days, it made sense for the user to directly use the $ vite CLI. But this has limitations: Vike should introduce its own CLI.

We'll most likely need a Vike CLI for #562, thus labeling as https://github.com/vikejs/vike/labels/server%20%F0%9F%8C%90. Also labelling as https://github.com/vikejs/vike/labels/high-prio%20%F0%9F%94%A5 because it's a blocker.

I would love Vike CLI!

IMO: If we were to do that, I thought it would be easier to use vike to depend on vite and install only vike, instead of having people install vite and vike separately.

If this seems different from Vike's design policy, please forget it.
