To account for the differences in VST2 plugins and VST3 modules we had to wrap most of our old functions from `src/plugin/utils.h` in a new `PluginInfo` struct that gathers all of this information while taking into account the differences between VST2 and VST3 plugins. With this change things are also a lot more organized. We can just query the plugin information we need rather than having to store things separately or having to recalculate things. This also moved the responsibility of all the weird `WINEPREFIX` behaviour to a single place instead of having it spread around `utils.pp`, the initialisation message, and `host-procoess.cpp`.
