Update mappings of gamepads affected by recent SDL change.

[divVerent]

This adds updated mappings for for changes in https://github.com/libsdl-org/SDL/commit/6f1f586086a18ab32ddccc05e4616aac02774a1b and https://github.com/libsdl-org/SDL/commit/de3909a190f6e1a3f11776ce42927f99b0381675

I have made a change to SDL to treat default Android mappings closer to reality and documentation on Android, by treating gamepads in which all of X, Y, Z, RX, RY, RZ axes exist to to return the axes in the order X, Y, RX, RY, Z, RZ.

See e.g. https://developer.android.com/develop/ui/views/touch-and-input/game-controllers/controller-input which documents Z and RZ to be for the right stick (and thus belonging together); also, a whole lot of Xbox-ish gamepads export the right stick as RX, RY opposing Google's documentation (but matching Linux's at https://www.kernel.org/doc/html/latest/input/gamepad.html) and the triggers as Z, RZ, which SDL's automatic mapping now handles.

This requires the changes to the mappings included in this commit - which adds them as extra mappings to not break with previous SDL versions. Note that it is quite possible that some of these gamepad entries could even be removed now; I cannot say for sure if any of the added mappings are optional or required. In particular some of the Xbox ones may be redundant with defaults but still differ from default by not mapping some buttons or axes.

I'm wary of version-specific breaking changes like this as

1. We try not to be too prescriptive of SDL version
2. Even though it says SDL on the tin, many (large) projects that don't use SDL but borrowed some of it's code at one point rely on these mappings

Would you consider amending your upstream patch to flip a GUID bit somewhere so that the necessary changes can coexist with older mappings, and future mapping submissions will expose the version difference to prevent collision ?

There is precedence for this, and it has tended to serve us well longer term. Obviously in the best case your future-forward proposal is sound, but the reality is messier.

Sent https://github.com/libsdl-org/SDL/pull/7444 to SDL - if that goes through, I'll update this PR accordingly - basically, restoring the previous line for every change, but changing the new one to have an 80 as the last SDLID byte.

Perfect, thank you for this !

[divVerent]

I'd prefer updating this one instead; no mappings seem entirely redundant, but some of the mappings MAY be unnecessary (they differ from default only by NOT mapping some buttons or axes that exist).

Will need squashing and rewording, though.

Will this be squashed to a single commit, or merged? If squashed, I'll edit the first post here and that should do, I guess?

[divVerent]

Comment adjusted - so if you squash, all should be fine.

FYI after these changes, the following are exact clones of SDL's default layout for Android, ignoring the "guide" button which many of these lack:

Some of these become redundant with this change (and thus end with 3f00, not 3f80), but most are pre-existing.

However, may still be worth keeping them as they help games that do NOT have a default mapping like SDL does. Especially as most of these sound like popular controllers.

Looks good, thanks
