Before this change, Base_directory was a char array. In general, it’s
better to use an std::filesystem::path to represent paths. Here’s why:
• char arrays have a limited size. If a user creates a file or directory
that has a very long path, then it might not be possible to store that
path in a given char array. You can try to make the char array long
enough to store the longest possible path, but future operating systems
may increase that limit. With std::filesystem::paths, you don’t have
to worry about path length limits.
• char arrays cannot necessarily represent all paths. We try our best to
use UTF-8 for all char arrays [1], but unfortunately, it’s possible to
create a path that cannot be represent using UTF-8 [2]. With an
std::filesystem::paths, stuff like that is less likely to happen because
std::filesystem::path::value_type is platform-specific.
• char arrays don’t have any built-in mechanisms for manipulating paths.
Before this commit, the code would work around this problem in two
different ways:
1. It would use Descent 3–specific functions that implement path
operations on char arrays/pointers (for example, ddio_MakePath()).
Once all paths use std::filesystem::path, we’ll be able to simplify
the code by removing those functions.
2. It would temporarily convert Base_directory into an
std::filesystem::path. This commit simplifies the code by removing
those temporary conversions because they are no longer necessary.

Removes key_emulation and joy_emulation toggles from ddio_init_info structures, that were not used in the SDL implementation.
All input is now handled using SDL for all platforms, alternatejoy/directinput options were only relevant for Windows-specific DirectInput. 'slowkey' was an unimplemented feature.
