[host1x] fix ffmpeg not having va-api on freebsd, inline nvenc (#3878)
- fix va-api not being used on freebsd small thingies dont affect a lot: - removes some pointer indirection (why save pointer to GMMU if its accesible via host1x) - use std::variant<> for decoder - miscelly vp9/v8/h264 opts Signed-off-by: lizzie <lizzie@eden-emu.dev> Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/3878 Reviewed-by: crueter <crueter@eden-emu.dev> Reviewed-by: MaranBr <maranbr@eden-emu.dev>
