media-sound/fluidsynth: add 2.4.6

* Use SDL3

  From the 2.4.4 release notes:
  > Support for SDL3 has been added, support for SDL2 has been deprecated [...]

  SDL2 support is going to be dropped in 2.5.0, so let's get a move on. Was
  going to change to SDL3 anyway but this is more of a push.

* Use cmake-multilib more idiomatically (spit into _all and such).

* Install an OpenRC init script (bug #450074).

* Add USE=openmp.

* Always build network support (bug #930788).

  It seems to be needed for pipewire/pulseaudio and I can't really see
  a reason to omit it anyway.
