Pull request overview

This PR refactors method names to follow the OpenTelemetry SDK naming convention for customizers. The changes deprecate the old setSpanNameExtractor and setStatusExtractor methods in favor of new setSpanNameExtractorCustomizer and setSpanStatusExtractorCustomizer methods, aligning with the naming pattern used in the SDK's AutoConfigurationCustomizer.

• Renamed customizer methods across the codebase to use "Customizer" suffix
• Added @Deprecated annotations to old methods that delegate to new ones
• Updated field names from "Transformer" to "Customizer" suffix for consistency
• Updated all instrumentation libraries and examples to use new method names
