The header of a Wii disc can be read from two places: The
unencrypted area at the beginning of the disc, or the beginning of
the game partition. The two copies are usually identical (except
for 0x60 and 0x61), but there are exceptions. For most of Dolphin's
history, we have been reading from the header inside the game
partition when getting metadata. This was however not the case
starting with 4.0-4901 and ending with 5.0-3762. This commit once
again makes Dolphin read metadata from the unencrypted header,
because of the following reasons that I recently was informed about:
- The "pink fish" disc has the game ID 410E01 in the unencrypted
header but the placeholder game ID RELSAB in the partition header.
- The revisions of some games differ between the two headers,
with the unencrypted one making more sense.
(See https://bugs.dolphin-emu.org/issues/11387)
For better or worse, this also means that sloppily hacked games where
only the game ID in the unencrypted header has been changed now will
use that modified game ID. And unlike with the partition header,
there is no signing or hashing that can tell us whether the
unencrypted header has been modified by someone other than Nintendo.
Since we don't have a way (AFAIK) to dynamically collect the list of
available art assets, we hardcode a list of gameids with available
artwork inside Dolphin. It's not great, but I don't think it's a
terrible solution either.
Art has to be manually uploaded to our Discord app configuration, and we
have a limit of ~150 assets, so most likely we'll limit ourselves to a
small set of popular games.

fixed crash from joining user that isn't hosting via a direct connection
current game stat can now pass to override the current game in config
uses ip endpoint from dolphin.org
ChunkFile doesn't use any of the file utilities, so we can drop these
headers to avoid pulling in unnecessary dependencies. This also
uncovered a few indirect inclusions.
Deduplicates code, and gets rid of some problems the old code had
(such as: bad performance when calling native functions, only one
disc showing up for multi-disc games, Wii banners being low-res,
unnecessarily much effort being needed for adding more metadata).
