[kernel][process][diagnostics] Use Reader handle table lock in ForEachHandle This is a minor optimization. No functional change. ProcessDispatcher::ForEachHandle iterates the handle table, calling T on each handle. ForEachHandle itself does not modify the table. T is passed a zx_handle_t and no existing callers attempt to modify the table. Change ForEachHandle to use a Reader lock since Writer is unnecessary. ProcessDispatcher::GetVmos must acquire the process's handle table lock before calling GetProcessVmosLocked as it iterates over the process's VMOs. However, GetProcessVmosLocked does not modify the handles or handle table so it does not need a Writer lock. Change GetVmos to acquire a Reader lock instead.
