[hle] Fixes for nxident, nxmp and nxplay, remove hbl.nsp workarounds (#3996)

adds `gpio` and `i2c` services
implements `IApplicationFunctions::SetMediaPlaybackStateForApplicatio`
stubs `IBtmSystemCore::GetDiscoveredAudioDevice`
implements `nvhost_ctrl_gpu::PmuGetGpuLoad` IOCTL (0x20)
implements `PSM::GetBatteryAgePercentage`, `PSM::GetBatteryVoltageState` and `PSM::GetBatteryChargeInfoFields`
implements `ISystemSettingsServer::GetConsoleInformationUploadFlag`, `ISystemSettingsServer::SetConsoleInformationUploadFlag`, `ISystemSettingsServer::GetAutomaticApplicationDownloadFlag`, `ISystemSettingsServer::SetAutomaticApplicationDownloadFlag`, `&ISystemSettingsServer::GetUsb30EnableFlag`, `ISystemSettingsServer::SetUsb30EnableFlag`
removes `hbl.nsp` specific workarounds
