improve codebase quality

- improve unreachable macro to print a message with a minor traceback then exit(0) instead of assert hackery
- add specific wine and dxvk directory methods
- rename dxvk install to download
- remove sanity asserts from lutris, caught by unreachable
- improve comments
- rename info to env
- only use a single buffer for information fetching
- fix formatting on code I had help on
- purge unused code
- if downloadToRam returns null pointer report that the archive went missing not that its invalid
- rename undescriptive "datadir" to be more specific
- remove unused code from when we stored the archive on disk
