ui: Improve ui-dev-server latency

- Make dev server multithreaded
- Don't bother scanning infra directory for changes.
- Avoid computing the abspath all the time

These last two reduce scan time from ~150ms to ~15ms on my machine
ninja -C foo ui on a clean build is 60ms so this is better than just
always running ninja.
