Currently, when traceback jumps from the system stack to a user stack (e.g., during profiling tracebacks), it leaves gp pointing at the g0. This is currently harmless since it's only used during profiling, so the code paths in gentraceback that care about gp aren't used, but it's really confusing and would certainly break if _TraceJumpStack were ever used in a context other than profiling. Fix this by updating gp to point to the user g when we switch stacks. For #54466.
