Provide a clear and concise description of the issue

FluidSynth shows up as an option for MIDI in the Libretro version of ScummVM, but not in the standalone/expert version.

Steps to Reproduce

• Launch ScummVM in the Expert menu
• Launch "~Run ScummVM"
• Tap the Global Options button
• Tap the MIDI tab
  • The GM Device dropdown on the libretro core lists three options: "Don't use General MIDI music", "Use first available device", and "FluidSynth".
  • That same dropdown on the standalone version is missing the "FluidSynth" option.
• Tap the Audio tab
  • The "Preferred Device" dropdown on the libretro core lists "<default>", "No music", "FluidSynth", "MT-32 emulator", "AdLib emulator", "PC Speaker emulator", "IBM PCjr emulator", and "Creative Music System" emulator.
  • That same dropdown on the standalone version is missing the "FluidSynth" and "MT-32 emulator" options.

Provide any additional context or information that may help us investigate your issue

I was able to select a soundfont (.sf2) file on the MIDI tab, but without being able to select a device to use it, it doesn't do me much good :)
