Fix use-after-free with interacting TracePoints
`vm_trace_hook()` runs global hooks before running local hooks.
Previously, we read the local hook list before running the global hooks
which led to use-after-free when a global hook frees the local hook
list. A global hook can do this by disabling a local TracePoint, for
example.
Delay local hook list loading until after running the global hooks.
Issue discovered by Jeremy Evans in GH-5862.
