Implement minimum_severity and trace_based logger configuration parameters

[Copilot]

This PR implements the logger configuration parameters specified in opentelemetry-specification#4612, adding support for minimum_severity and trace_based filtering in the Java SDK logging implementation.

Changes

Core Implementation

• Enhanced LoggerConfig: Added minimumSeverity (int) and traceBased (boolean) parameters with AutoValue support
• Updated SdkLogger: Modified to store and apply new configuration parameters in isEnabled() checks and configuration updates
• Enhanced log record builders: Updated both SdkLogRecordBuilder and ExtendedSdkLogRecordBuilder to apply filtering logic in their emit() methods

Filtering Logic

• Minimum severity filtering: Log records with severity below the configured minimum are dropped (except UNDEFINED_SEVERITY_NUMBER which passes through)
• Trace-based filtering: When enabled, log records not associated with sampled traces are dropped (records without valid span context pass through)
• Dual application: Filtering is applied in both isEnabled() (for optimization) and emit() (for safety) as specified

API Enhancements

• Added convenience methods: LoggerConfig.withMinimumSeverity(int) and LoggerConfig.withTraceBased()
• Maintained full backward compatibility with existing LoggerConfig usage
• Preserved existing constructor signatures with overloaded versions

Example Usage

// Set minimum severity to WARN
SdkLoggerProvider.builder()
    .addLoggerConfiguratorCondition(nameEquals("com.example.*"), 
        LoggerConfig.withMinimumSeverity(Severity.WARN.getSeverityNumber()))
    .build();

// Enable trace-based filtering
SdkLoggerProvider.builder()
    .addLoggerConfiguratorCondition(nameEquals("sensitive.*"), 
        LoggerConfig.withTraceBased())
    .build();

// Combine both parameters
SdkLoggerProvider.builder()
    .addLoggerConfiguratorCondition(nameEquals("production.*"), 
        LoggerConfig.create(true, Severity.ERROR.getSeverityNumber(), true))
    .build();

Testing

• Added comprehensive test coverage for all new filtering scenarios
• Verified isEnabled() method behavior with new parameters
• Ensured backward compatibility with existing configurations
• All existing tests continue to pass without modification

This implementation follows the OpenTelemetry specification exactly, providing efficient log filtering capabilities while maintaining the existing API contract.
