Font size adjustments (#7185)

Adjust and rename the function `pointSize` so that it sets the font size in pixels. Rename `pointSize` to `adjustedToPixelSize` because that's what it does now. It returns a font adjusted to a given pixel size. Rename `fontPointer` to `font` because it's not a pointer but a copy. Rename `fontSize` to simply `size`.

This works if the intended model is that users use global fractional scaling. In that case pixel sized fonts are also scaled so that they should stay legible for different screen sizes and pixel densities.

## Adjust plugins with regards to adjustedToPixelSize

Adjust the plugins with regards to the use of `adjustedToPixelSize`.

Remove the explicit setting of the font size of combo boxes in the following places to make the combo boxes consistent:
* `AudioFileProcessorView.cpp`
* `DualFilterControlDialog.cpp`
* `Monstro.cpp` (does not even seem to use text)
* `Mallets.cpp`

Remove calls to `adjustedToPixelSize` in the following places because they can deal with different font sizes:
* `LadspaBrowser.cpp`

Set an explicit point sized font size for the "Show GUI" button in `ZynAddSubFx.cpp`

Increase the font size of the buttons in the Vestige plugin and reduce code repetition by introducing a single variable for the font size.

I was not able to find out where the font in `VstEffectControlDialog.cpp` is shown. So it is left as is for now.

## Adjust the font sizes in the area of GUI editors and instruments.

Increase the font size to 10 pixels in the following places:
* Effect view: "Controls" button and the display of the effect name at the bottom
* Automation editor: Min and max value display to the left of the editor
* InstrumentFunctionViews: Labels "Chord:", "Direction:" and "Mode:"
* InstrumentMidiIOView: Message display "Specify the velocity normalization base for MIDI-based instruments at 100% note velocity."
* InstrumentSoundShapingView: Message display "Envelopes, LFOs and filters are not supported by the current instrument."
* InstrumentTuningView: Message display "Enables the use of global transposition"

Increase the font size to 12 pixels in the mixer channel view, i.e. the display of the channel name.

Render messages in system font size in the following areas because there should be enough space for almost all sizes:
* Automation editor: Message display "Please open an automation clip by double-clicking on it!"
* Piano roll: Message display "Please open a clip by double-clicking on it!"

Use the application font for the line edit that can be used to change the instrument name.

Remove overrides which explicitly set the font size for LED check boxes in:
* EnvelopeAndLfoView: Labels "FREQ x 100" and "MODULATE ENV AMOUNT"

Remove overrides which explicitly set the font size for combo boxes in:
* InstrumentSoundShapingView: Filter combo box

## Adjust font sizes in widgets

Adjust the font sizes in the area of the custom GUI widgets.

Increase and unify the pixel font size to 10 pixels in the following classes:
* `ComboBox`
* `GroupBox`
* `Knob`
* `LcdFloatSpinBox`
* `LcdWidget`
* `LedCheckBox`
* `Oscilloscope`: Display of "Click to enable"
* `TabWidget`

Shorten the text in `EnvelopeAndLfoView` from "MODULATE ENV AMOUNT" to "MOD ENV AMOUNT" to make it fit with the new font size of `LedCheckBox`.

Remove the setting of the font size in pixels from `MeterDialog` because it's displayed in a layout and can accommodate all font sizes. Note: the dialog can be triggered from a LADSPA plugin with tempo sync, e.g. "Allpass delay line". Right click on the time parameter and select "Tempo Sync > Custom..." from the context menu.

Remove the setting of the font size in `TabBar` as none of the added `TabButton` instances displays text in the first place.

Remove the setting of the font size in `TabWidget::addTab` because the font size is already set in the constructor. It would be an unexpected size effect of setting a tab anyway. Remove a duplicate call to setting the font size in `TabWidget::paintEvent`.

Remove unnecessary includes of `gui_templates.h` wherever this is possible now.

## Direct use of setPixelSize

Directly use `setPixelSize` when drawing the "Note Velocity" and "Note Panning" strings as they will likely never be drawn using point sizes.
