module: Add module_for_each_mod() function

The tracing system needs a way to save all the currently loaded modules
and their addresses into persistent memory so that it can evaluate the
addresses on a reboot from a crash. When the persistent memory trace
starts, it will load the module addresses and names into the persistent
memory. To do so, it will call the module_for_each_mod() function and pass
it a function and data structure to get called on each loaded module. Then
it can record the memory.

This only implements that function.
