tdf#101854 Move to CommonSalLayout removed faux bold in macos

Previously faux bold was drawn with setting a dictionary key
kCTStrokeWidthAttributeName and a value of the stroke width. This
stopped working because we don't use attributedString for drawing
anymore but we always use CTFontDrawGlyphs and draw the glyphs,
which doesn't have a way to set this attributes.

It took me a while to find a workaround (thanks to Apple's great
documentation), where we switch text drawing to fill and stroke,
and after that we can modify the stroke by changing the line
width.
