Proc: Use selections consistently
...
All `proc_*` passes now use the same module and process for loops, using `design->all_selected_modules()` and `mod->selected_processes()` respectively.
This simplifies the code, and makes the couple `proc_*` passes that were ignoring boxed modules stop doing that (which seems to have been erroneous rather than intentional).

sim.cc: Move cycle check
...
Calling `throw dst_end_of_data_exception()` when the desired number of cycles has been reached means that the fst reader can't tidy up after itself and leads to memory leaks.
This doesn't happen when the `-stop` flag is used because the `Yosys::FstData` struct tracks the end time and skips the outer callback if the simulation has gone past the desired end time.
Move cycle checking into the inner callback along with the time checking means that the outer callback no longer needs to throw an exception in order to stop checking further values, while still allowing the fst reader to finish reading and deallocate memory.

Fix Crashes with GCC 15 #5088
...
When building `WITH_PYTHON`, where a global list of modules is maintained, deleting a module also erases the entry in said global list. This can lead to memory corruption if the global list is destructed before the module.
Using `on_shutdown()` instead means the module destructor is explicitly called before the global list can be destructed, preventing the issue.
Also add a comment to `Pass::~Pass()` to suggest the same for future passes that might try to use that (and see this commit in the blame if they need a reason why).
