6588: Add default argument to `CDataFileReader/IMap::GetItem` r=def- a=Robyt3

Add default value `nullptr` for `int *pType` and `int *pID` output parameters of `GetItem` functions.

Use `nullptr` instead of `0`.

## Checklist

- [ ] Tested the change ingame
- [ ] Provided screenshots if it is a visual change
- [ ] Tested in combination with possibly related configuration options
- [ ] Written a unit test (especially base/) or added coverage to integration test
- [ ] Considered possible null pointers and out of bounds array indexing
- [ ] Changed no physics that affect existing maps
- [ ] Tested the change with [ASan+UBSan or valgrind's memcheck](https://github.com/ddnet/ddnet/#using-addresssanitizer--undefinedbehavioursanitizer-or-valgrinds-memcheck) (optional)


6589: Fix heap-use-after-free when quitting/restarting r=def- a=Robyt3

Items and particles were also rendered in the client states quitting and restarting, which was causing accesses to the already freed map data.

Closes #6387 until further notice.
