fix(browser): Improve navigation vs. redirect detection

[Lms24]

This PR attempts to improve our navigation root vs. navigation.redirect child span detection logic in the default browserTracingIntegration:

• Increase the threshold of inactivity between potential navigations from 300ms to 1.5s
• Change how we treat interactions:
  • Previously, we'd take interactions happening before the last root span was started into account
  • Now, we reset the interaction timestamp when we start a new navigation root span. So from that moment on, we'll consider every new navigation span a redirect iff:
    • no interaction happened within 1.5s (from root span start)
    • the new span was started within 1.5s
    • there is still an active root span

I was a bit confused about the previous logic of interaction timestamps, including the tests. So in attempt to clear it up, I also renamed and slightly reworked the tests. Also added a couple of new ones, including one that tests a series of redirects and navigations. Chances are though, that I'm missing an important detail why we reused interaction timestamps prior to the last root span.

First part of #17282. From this issue, we should still consider bringing this functionality to all BT integrations but one step at a time :)
