Add tooltips to fxmixer faders

Browse Source 
Added tooltips to show the actual value when moving the fader handle.
This works mostly like the same feature we already have for the volume
knobs. Depending on settings the value is shown in a range between
0% to 200% or -inf/-34dBV to 6.02 dBV. Again that's the same as for the
volume knob. Value range could be adjusted easily if necessary.

Closes #3305914.
