Andreas Kling 239b9d8662 LibJS: Manually limit the recursion depth in Proxy ...

Instead of relying on native stack overflows to kick us out of circular
proxy chains, we now keep track of the recursion depth and kick
ourselves out if it exceeds 10'000.

This fixes an issue where compiler tail/sibling call optimizations would
turn infinite recursion into infinite loops, and thus never hit a stack
overflow to kick itself out.

For whatever reason, we've only seen the issue on SerenityOS with UBSAN,
but it could theoretically happen on any platform.
