Launcher with game import; ship the shareware episode instead of Freedoom

DOOM now opens on a game list. The package bundles id's freely
distributable shareware DOOM1.WAD; players add The Ultimate DOOM, DOOM II,
TNT and Plutonia (or Freedoom) from their own files:

- copied into /data/homebrew/PPSA99666/wads, as WADs or inside ZIP, 7Z or
  RAR archives, which are imported once at the next start;
- downloaded from an http:// or https:// link typed on the system
  keyboard: a WAD, an archive, or a folder listing to pick from. Archives
  are read in place over HTTP range requests, so a large solid 7Z needs no
  room on the console beyond the game WADs it holds.

The console uses sceHttp/sceSsl and the IME dialog; the PC build uses
libcurl. Archives go through libarchive, liblzma and zlib, fetched pinned
and built for both targets, with large allocations taken from mmap.

Engine fixes that came with it: IdentifyVersion takes the launcher's
choice and sets gamemission, so TNT and Plutonia get their own level names
and finale texts; the sky check no longer gives The Ultimate DOOM the
DOOM II skies; saves are per game; widescreen full-screen pictures from the
2024 re-release are drawn centred instead of rejected.

The console test runner receives doom.log over the capture connection
instead of reading the kernel log.
