Span/log processors and PeriodicMetricReader use static ComponentId, causing all instances to share otel.component.name "<type>/0" #9012

Description

In the following classes, COMPONENT_ID is declared as private static final ComponentId instead of an instance field:

• opentelemetry-java/sdk/trace/src/main/java/io/opentelemetry/sdk/trace/export/BatchSpanProcessor.java

  Lines 47 to 48 in be7de06

  	private static final ComponentId COMPONENT_ID =
  	ComponentId.generateLazy("batching_span_processor");

• opentelemetry-java/sdk/trace/src/main/java/io/opentelemetry/sdk/trace/export/SimpleSpanProcessor.java

  Line 41 in be7de06

  private static final ComponentId COMPONENT_ID = ComponentId.generateLazy("simple_span_processor");

• opentelemetry-java/sdk/logs/src/main/java/io/opentelemetry/sdk/logs/export/BatchLogRecordProcessor.java

  Lines 45 to 46 in be7de06

  	private static final ComponentId COMPONENT_ID =
  	ComponentId.generateLazy("batching_log_processor");

• opentelemetry-java/sdk/logs/src/main/java/io/opentelemetry/sdk/logs/export/SimpleLogRecordProcessor.java

  Line 42 in be7de06

  private static final ComponentId COMPONENT_ID = ComponentId.generateLazy("simple_log_processor");

• opentelemetry-java/sdk/metrics/src/main/java/io/opentelemetry/sdk/metrics/export/PeriodicMetricReader.java

  Lines 46 to 47 in be7de06

  	private static final ComponentId COMPONENT_ID =
  	ComponentId.generateLazy("periodic_metric_reader");

Because COMPONENT_ID is static, ComponentId.generateLazy(...) is only invoked once per class load, so every instance of BatchSpanProcessor, SimpleSpanProcessor, BatchLogRecordProcessor, SimpleLogRecordProcessor, or PeriodicMetricReader in the JVM reports <type>/0 for otel.component.name (unlike GrpcExporterBuilder and HttpExporterBuilder, which call ComponentId.generateLazy(...) per exporter instance).

Expected behavior

Each processor and metric reader instance should generate its own ComponentId (<type>/0, <type>/1, ...) so otel.component.name uniquely identifies each instance.
