[DevTools] Filter out built-in stack frames (facebook#34828)

Treat fake eval anonymous stacks as built-in. Hide built-in stack frames
unless they're used to call into a non-ignored stack frame.

The two main things to fix here is that 1) we're showing a linkified
stack for fake anonymous and 2) we're showing only built-ins when the
stack is completely internal. Meaning framework code is all noise.
