the Xcode project needs updating

[Ozkan Sezer]

Xcode project needs updating for both SDL2 and SDL3 branches:

• wavpack option should be enabled: MUSIC_WAVPACK must be defined

• A wavpack project must be created, like the others, and must be
  integrated in the main SDL_mixer project (like the others..)

A job for @slouken (can't do myself.)

@slouken: wavpack.framework seems to be missing in prerelease 2.7.2 dmg

Fixed for release, thanks!

I minorly updated our vendored libgme (game-music-emu): the submodule should point to commit cdd021507518162a4884898bbac85cbd32ed7a77 -- please make sure your copies are updated.

[Sam Lantinga]

Please don't do that when we have a release candidate pending unless it's a critical fix. If it's not necessary for release, can you please revert until next week?

It is a build fix: libsdl-org/game-music-emu@cdd0215
If you're sure, yes I can easily revert

Okay, that looks fine, but in general once a pre-release tag is added to a project, that code is frozen except for critical bug fixes until release. We don't want to introduce any regressions between the time the public tries out the release candidate and the final release.
