Patches needed to fix the Fedora rawhide build

[dreua]

I feel like those three PRs in different repos should have on issue to link them all together and add some context so where we go:

• Add header to define memset mupen64plus-audio-sdl#46
• debugger: Add missing include mupen64plus-ui-console#91
• Fix include order mupen64plus-video-glide64mk2#137

I can't really say what caused this builds to fail, likely triggers are the switch from sdl2 to sdl2-compat (if I understand correctly that is sdl3 with a compatibility layer) and maybe gcc/libstd/whatever which has been upgraded from 14 to 15.

Here you can see all the build environment and how it changed:
https://koschei.fedoraproject.org/package/mupen64plus?collection=f42 (see builds on 2025-01-14 and -16)

It is likely that other people on other platforms will have the same issues sooner or later, therefore I provided these PRs.

The error messages leading to those changes can probably still be collected from the build system's logs, let me know if you think that is worth it, I could add them to this issue for reference (and maybe search indexing).
