Make tracepoints with set_trace_func or TracePoint.new ractor local (#15468)
Before this change, GC'ing any Ractor object caused you to lose all
enabled tracepoints across all ractors (even main). Now tracepoints are
ractor-local and this doesn't happen. Internal events are still global.
Fixes [Bug #19112]
