Summary

This PR adds some new platform functions around global directories and fixes up an existing one.

plat_get_global_config_dir looks like it had been started before, but it assumed a particular buffer size and would wipe out your stack if the buffer was < 1024 bytes. This has been corrected and now a buffer length must be specified.

plat_get_global_data_dir was added for a global data directory.

plat_get_temp_dir was added as a way to get a temporary directory to store files or data. This mostly utilizes OS-level temporary directories.

On macOS, we will from this point forward standardize on using 86Box for application-specific directories instead of the reverse domain identifier. This makes things more consistent across platforms. For example, the global application data location will be ~/Library/Application Support/86Box and the global config directory will be ~/Library/Preferences/86Box.

As part of the move toward the consistent application data directory name, ~/Library/Application Support/86Box will also be a valid ROM search path. The existing ROM search path is still in place.

The platform function updates were also added and updated on the SDL side as well.
