GSCapture: add volume slider and scale recorded audio
Description of Changes
Fixes #12700
- Added an audio capture volume slider
- Made a new AudioCaptureVolume setting stored in GS config, defaulting to 80%.
- Applied the volume multiplier when feeding samples to the FFmpeg encoder
Originally I was going to add libavfilter but I couldn't justify adding that library for one feature so that's why I did this the way I did.
Rationale behind Changes
Giving users a volume control makes built-in recording behave more like standard capture tools where mic/system levels can be balanced before hitting "Record."
Suggested Testing Steps
- Start a capture with default settings, then inspect the resulting video to confirm the recorded audio is quieter than before.
- Change the slider to e.g. 50% and 100%, capture again, and confirm the output volume scales accordingly for the video capture
