chore(build): refactor and increase sanity

now all packages only use other built packages, no source imports.

- upgrade typescript + fixups
- add a version override so the API extractor uses the same TS version
- make typescript use bundler semantics for imports
- remove most TS path overrides, keep only per-package internal ones
- change build for qwik-labs to use vite + dts plugin
- build types and api in steps: qwik, then qwik-city+qwik-react, then the rest
- change the dev server to remove workarounds
- add flag to disable vendor scan, was causing e2e issues
- some type fixes
