Fix SpotBugs FE_FLOATING_POINT_EQUALITY warnings
Refactored to use `com.codename1.util.MathUtil.compare` for floating point comparisons to avoid using `Float.compare` and `Double.compare` which are not available in CLDC 1.1. Added `compare` methods to `com.codename1.util.MathUtil`. Fixed `FE_FLOATING_POINT_EQUALITY` warnings in: - CodenameOne/src/com/codename1/ui/geom/GeneralPath.java - CodenameOne/src/com/codename1/ui/plaf/CSSBorder.java - CodenameOne/src/com/codename1/ui/plaf/RoundRectBorder.java - CodenameOne/src/com/codename1/charts/models/XYSeries.java - CodenameOne/src/com/codename1/charts/models/XYValueSeries.java - CodenameOne/src/com/codename1/location/Location.java - CodenameOne/src/com/codename1/ui/Command.java - CodenameOne/src/com/codename1/ui/Stroke.java - CodenameOne/src/com/codename1/ui/layouts/LayeredLayout.java - CodenameOne/src/com/codename1/ui/plaf/Border.java Updated `generate-quality-report.py` to enforce this rule in CI.
