Update to Mixxx version 2.4 with updated dependencies

[djantti]

Mixxx 2.4 is nearing release, so I'm already submitting this PR in hopes that it will be tested, reviewed and ready to go as close to final release day as possible. At the moment it's using the 2.4 git branch, but I'll update the manifest once the 2.4 tarball is available.

Changes include:

• Update to Mixxx 2.4 with new dependencies
• Slightly reorganized manifest file
• Use Wayland by default
• Existing dependencies updated to latest versions
• Everything checked for unused build options and features
• RelWithDebInfo build type for all CMake modules
• More unnecessary binaries and config files removed

I've tested my local build of this flatpak fairly extensively and used it on gigs without issues. Version 2.4 is a big update for Mixxx, so let me know if anything should be changed or improved. Happy DJing!

Looks like the bot is happy! I did a quick run and things appear to be working. Only problem is that LV2 plugins are no longer listed, so I'll add back the LV2_PATH environment variable. After that I'll ask folks to test the build as much as they can.

[hfiguiere]

the problem is the wrapper script is missing the export statement. (see at bottom of the manifest)

[hfiguiere]

we probably did never notice because there was the --env.

[djantti]

Ah yes, good catch! That is a better fix.
