RFR: 8165943: LineBreakMeasurer does not measure correctly if TextAttribute.TRACKING is set. [v5]

[Olga Mikhaltsova]

> This is a fix for LineBreakMeasurer. It takes into account the TextAttribute.TRACKING value (not eq 0) while calculating the line breaks.
> 
> Tested on Linux x64, Windows x64, macOS x64 with the reproducer (LineBreakSample.java) attached to JDK-8165943 and the following group of tests:
> `$JTREG_HOME/bin/jtreg -jdk:$BUILD_HOME ./test/jdk/java/awt/font`
