QMacStyle: Set WA_MacShowFocusRect for checkbox, radio button

Browse Source 
This fixes small and mini checkbox and radio button
focus rings since the previous HITheme removal patch
(90c9370d50). But also allows to properly draw
the focus ring outside the widget's boundaries, as
it's common in macOS.

More importantly, we pave the way to use QFocusFrame
for most widgets and, eventually, implement the focus
ring animation.

Finally, we tweak the spacing between the indicators
and their respective label.
