Don't check lfQuality in LOGFONT as it has no effect on rendering

Remove the LOGFONT lfQuality check in computePaintTextFlags and instead
base the textFlags entierly on the system ClearType settings (and
whether a font is a web font). Skia will then use this information to
pick the appropriate type of font smoothing to apply (if any).
