Fix remaining SpotBugs UC_USELESS_CONDITION warnings

Fixed multiple instances of 'Condition has no effect' (UC_USELESS_CONDITION) in core classes:
* CodenameOne/src/com/codename1/util/MathUtil.java: Fixed bitwise shift logic in `ieee754_pow` (`>>>` to `>>`) to restore correct negative number handling.
* CodenameOne/src/com/codename1/ui/MenuBar.java: Removed redundant `COMMAND_BEHAVIOR_ICS` check.
* CodenameOne/src/com/codename1/ui/Component.java: Removed duplicate `!animateBackground` check.
* CodenameOne/src/com/codename1/ui/ComponentGroup.java: Removed redundant `if (count > 1)` check.
* CodenameOne/src/com/codename1/ui/html/CSSParser.java: Removed redundant whitespace check.
* CodenameOne/src/com/codename1/ui/html/HTMLComponent.java: Removed redundant whitespace check.
* CodenameOne/src/com/codename1/xml/XMLParser.java: Removed redundant whitespace check.
* CodenameOne/src/com/codename1/ui/html/CSSEngine.java: Removed redundant whitespace check.
* CodenameOne/src/com/codename1/impl/CodenameOneImplementation.java: Refactored `setCommandBehavior` condition logic.
