qt: Fix font size and scaling issues (#3734)
* qt: Make sure font size in MasternodeList gets scaled as expected

* qt: Make sure font size in ShutdownWindow gets scaled as expected

* qt: Drop obsolete application font updates

* qt: Scale QMenu and QMessageBox globally

To make sure non-custom context menus + QMessageBox instances createy by
static calls like QMessageBox::critical are scaled also.

* qt: Avoid redundant scaling for tooltips and menus

* qt: Only update widget's font if required

* qt: Merge GUIUtil::mapFontSizeUpdates into GUIUtil::mapNormalFontUpdates

* qt: Remove obsolete setFixedPitchFont call

* qt: Use setFixedPitchFont in SendCoinsEntry

* qt: Scale font size in increments of 0.25

* qt: Properly scale network traffic stats depending on font metrics

* qt: Update min/max width of OptionsDialog depending on buttons width

* qt: Emit a signal whenever any attribute of AppearanceWidget changed

* qt: Update OptionsDialog width if the appearance changed

* qt: Calculate the initial wide right after the window showed up

Make sure the visibility state of the widgets is correct before width calculations.

* qt: Call parent class showEvent + override it explicit

* qt: Let OptionsDialog emit a signal if appearance gets changed

* qt: Resize main toolbar depending on visible buttons / font attributes

* qt: Reset max width after it has been set to still allow window resizing

* qt: Properly update the weight of widgets with default font attributes

* qt: Handle updates to the font attributes

* qt: Use resize() instead of setMaximumWidth()

Co-authored-by: UdjinM6 <UdjinM6@users.noreply.github.com>

* qt: Call GUIUtil::updateFonts in ModalOverlay constructor

* qt: Make sure default fonts are stored properly for the related widget

* qt: Ignore some low level classes in GUIUtil::updateFont

* rpc: Remove obsolete `.arg()` call

* qt: Drop fixedPitchFont

* qt: Avoid redundant font updates. Let GUIUtil::updateFont handle them

* qt: Scale recent transactions on OverviewPage

They were scaled by font inheritance before

* qt: Ignore QListView in GUIUtil::updateFonts
