LibWeb: Implement performance.timeOrigin

This is the origin timestamp of the same monotonic clock used for the
performance.now() timestamp.

I got a little confused while implementing this, since the numbers are
very low. That's because it uses the CLOCK_MONOTONIC system clock,
which we start counting from 0 at boot. :^)
